Crimes occur every day from burglary, to killings, kidnapping, stealing, and many more. The people that commit those kind of crimes need to be caught so that they can pay their consequences which should help them realize the crime they committed was wrong. Catching a criminal is not easy so what are the most effective ways to catch a criminal? The forensic community plays an important role in helping out with this situation. Forensic scientist help law enforcements get a lead and solve a case. Forensic scientists use different devices like urine testing, DNA testing, DNA markers, and many more devices to help get a lead in a case in order to come to the decision of convicting the right person. Forensics technology has improved greatly over time
DNA
In most cases the easiest way to catch a criminal is by DNA. With DNA in a criminal case it can put you at the place of crime. There are some flaws with DNA though. There is always the possibility of people having the same DNA strands. And if a piece of hair or any other kind of DNA is found at a crime scene and that is the only evidence and two people have the same DNA strand there’s a possibility of the wrong person going to jail.
Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any DNA at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not a long time ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Also since the…...

A Game to Catch

...A game of catch-up The shift in economic power from West to East is accelerating, says John O’Sullivan. The rich world will lose some of its privileges Sep 24th 2011 | from the print edition * * QUARRY BANK MILL is a handsome five-storey brick building set in the valley of the river Bollin at Styal, a small English village a few miles south of Manchester. It was built in 1784 by Samuel Greg, a merchant, who found profit in supplying cotton thread to Lancashire’s weavers. The raw cotton shipped from America’s slave plantations was processed on the latest machinery, Richard Arkwright’s water frame. Later Greg extended the factory and installed coal-fired steam engines to add to the water power from the Bollin. All this gave a huge boost to productivity. In 1700 a spinster with a pedal-driven spinning wheel might take 200 hours to produce a pound of yarn. By the 1820s it would take her around an hour. Greg’s mill was part of a revolution in industry that would profoundly alter the world’s pecking order. The new technologies—labour-saving inventions, factory production, engines powered by fossil fuels—spread to other parts of western Europe and later to America. The early industrialisers (along with a few late developers, such as Japan) were able to lock in and build on their lead in technology and living standards. The “great divergence” between the West and the rest lasted for two centuries. The mill at Styal, once one of the world’s largest, has become a......

To Catch a Thief

...might find the tone engaging or the content interesting, and it encourages us to read it quickly, not ask questions, and disseminate it to our friends. Of course, there’s more to it than that, but the point is, really, that we need an consciousness that is aware and alert to how reading, writing, and our accessed to both changed when they went online. The part of Lui’s definition I found particularly helpful engages “the usage side of the continuum, specific topics of interest include: browsing, searching, scanning, jumping, filtering, aggregating, organizing, and other kinds of discontinuous, low-attention, peripheral-vision, or machine-assisted reading practices that only partially map over predecessor practices of literacy. But also: new ways to focalize or intensify reading among the clutter (as in the ability of RSS and similar tools to create a virtual “my newspaper”).,” The emphasis on how our attention is divided and diluted by the many, many possibilities the webbiness of the web offers us is, I think, the crux of the “trouble” with online reading practices. The advantages can often function as disadvantages when there isn’t a conscious effort to make these things work for us instead of distract us. I guess this stuck out to me particularly because I personally am so prone to distraction in any setting, so the constant struggle I have to focus on and finish a text that I am either reading or writing on an electronic platform is a huge factor in how I operate.

Catch 22

...Catch 22 Mr. Secretary, By your request I have researched the directive known as Catch 22. After extensive research through various sources, I am now able to present you with the information I have gathered. I will first define the term for you then I will explain what I see as the best solution to your proposal of its reinstatement. A Catch 22 is essentially a paradox by which a statement leads to the contradiction of that very statement. The term Catch 22 was coined by Joseph Heller and refers to the US Army clause 22 which states: “All persons with mental issues should be removed from active combat upon request; however, requesting removal from active combat is a sign of mental stability as it is the self preservation function of the brain working.” An individual’s recognition of his mental state shows his cognitive ability to understand and value his own safety, therefore, making his mentally capable of the duties at hand. So you see, Mr. Secretary, the Catch 22 is a very assuming and entrapping clause that only takes into account one’s ability to recognize self-preservation. As defined above, the Catch 22 directive is an entrapment tool that was used by the US Armed Forces to avoid losing capable soldiers in a time of high stakes and world war. Mr. Secretary, I believe your interest in re-instituting this clause must have been stifled by the above mentioned; however, if you believe there is sufficient reason to press on with this proposal, allow me to curb your......

To Catch a Predator with a Predator

...To Catch a Predator with a Predator The business of exploitation television and the ethical considerations stemming from such programming are never clearer than in the show “To Catch a Predator.” Under the guise of catching criminals in the act and exposing sexual predators the networks (NBC and MSNBC) carried out a show of sting operations bolstered by the journalistic credibility of Chris Hansen who had reported for NBC Dateline previously. I argue that the predatory nature with which the program was carried out not only may have violated the civil rights of both the victims and the target sex predator but even more so sets up a dilemma as it pertains to the journalism profession. Additionally, privacy was likely invaded for both parties involved before any crime was committed, bringing entrapment into the conversation. Let me first address the subject of civil rights as a matter of privacy insomuch as it relates to getting a fair trial. In our justice system an individual must be presumed innocent until proven guilty beyond a reasonable doubt when he or she is charged with a crime. By placing someone’s face on television prior to the trial where that must be proven, it has great potential to and some would argue that it is likely to taint a jury. Obviously, situations of publicity cannot be avoided altogether. However, the intentional use of such footage to anchor a television show may not fall into that category of those which cannot be avoided. Ultimately on this......

Catch-22

...Catch-22 “You wouldn’t be normal if you were never afraid. Even the bravest men experience fear. One of the biggest jobs we all face in combat is to overcome fear.”(ch. 9) In times where desperate times call for desperate measures, the novel Catch-22, writing by Joseph Heller, follows the life of a B-25 fighter pilot named John Yossarian, in addition to other members of his squadron. Yossarian is the key protagonist of the novel who finds a more important mission than the one assigned to him while in the air force, and this is to preserve his own life at all costs. Over the course of this novel, this young man finds himself stationed on a small island of Pianosa, off the west coast of Italy, in the Mediterranean Sea. Placed under the command of Major Major, and Major De-Coverley, as well as General Dreedle, Yossarian now finds himself faced with the predicaments of an overbearing and abusing bureaucracy, as well as the contemplation of sanity vs. insanity as his ticket out of this station. The theme to be best directed with Catch-22 is the unknowing between truth and falsehood. In addition to that, is the blind sight between who are really your friends, and your enemies. Joseph Heller presents a vast arrangement of symbolism in the novel. First and foremost being the man in the white cast at the start of the novel. When he was brought to the hospital, the other men viewed him in such a way that it was ignored that he was a man, but was seen more as a viewing...

Catch Me If You Can

...Catch Me if You Can: An Entertaining Roller Coaster Ride Imagine having the ability to become an airline co-pilot, a doctor, and a lawyer all before turning the age of twenty-one. Well believe it or not; this became a reality for Frank Abagnale Jr. as he infiltrated the system in the 1960’s. The Steven Spielberg directed movie “Catch Me if You Can” brings out this true story, in which a sixteen year old runaway Frank Abagnale Jr. (played by Leonardo Dicaprio) began his “brilliant three year run as a master of deception” (Hollywood.com). In this three year stint, he also forges over a million dollars of fake checks across the country, creates several aliases for himself, and manages to become the youngest person on the FBI’s Most Wanted list. Carl Hanratty, an FBI Bank Fraud Agent (played by Tom Hanks) engages with Abagnale Jr. in what Starpulse.com calls a “a highly enjoyable cat-and–mouse escapade.” After Frank Abagnale Jr. was eventually caught, Carl Hanratty realized that Abagnale’s check-savviness could be a benefit to his department in the FBI. He later went on to have a successful career as an FBI Agent in Check Fraud, instead of facing a timely prison sentence. The movie flows well due to a plethora of acting skills, well-written dialogue, and an entertaining back and forth battle that Abagnale Jr. encounters with Hanratty and also within himself. “Catch Me’s acting shines,” Hollywood.com raves. The movie contains a respectable and veteran class of Hollywood......

The novel mainly states the reasons of starting of the Rastafarianism (Farley, 2006, pg. 216). It is known that Rastafarianism played a very huge role in the life of Bob Marley.

To Catch a Dream

...Floyd Ogle Instructor: English 1A 11 September 2008 To Catch a Dream On August 28, 1963 Dr. Martin Luther King Jr., possibly one of the most eloquent, and certainly one of the most passionate men to ever share his heart, delivered a stunning and earth shaping speech. He delivered this speech not only to over 200,000 people in attendance at the Lincoln Memorial, and not even to a nation struggling with the perils of racism and equality, but to generations of people who share in a dream and strive for freedom; a dream that many still dream today. Even though we are closer now than at any point in history, we have yet to experience the freedom of which Dr. King dreamed. Racism is not a problem only in America, most every nation deals with racial issues on some level. Though none of us could ever forget the tragedy of the Holocaust, we tend to forget that it was racially motivated. Hitler’s goal was to exterminate the Jewish people. “Anne Frank was murdered by the Nazis in Bergen-Belsen [concentration camp] for being a Jew, just one of over one million Jewish children to be killed in the Holocaust” (Melchior). The Holocaust, while the most prominent, is not the only example of ethnic cleansing that the world offers. Darfur, the Sudan, Croatia, and Kosovo, just to name a few, have all dealt with this racial horror. South Africa, as well, deals with racism. As the political power shifts toward black South Africans, white South Africans face continual racial......

Catch in the Rye

...corrupt. He will always be in Holden’s mind a little boy not affected by the dirty hands of society. Pheobe, on the other hand, will have to enter the world sooner or later and then she too will become corrupt. D.B., though, has already submitted to that corruption by “selling out” to the movies. Holden realizes that D.B. has given his story to the movie business and does not like it because he wanted his brother to continue writing the little stories he loved so much. Pheobe, diametrically, has not yet been absorbed by society but is on her way and Holden nor anyone else can stop her. Holden finds corruption in almost everything he sees but does not yet even realize that he too is part of that corrupt world the minute he stopped being a child and wanting to be an adult. By doing many of the things he does he displays a desire to grow up, to act mature, to ultimately blend in with society but he is restricted by his ideals of innocence. The way he orders his drinks, dances with the two ladies in the hotel, and sends his money frivolously shows how Holden has accepted the reality of being an adult but can not come to terms with the fact that all children will also enter Holden’s corrupt society. Holden’s basic description of a corrupt person is a phoney. This characterization is often harsh and unjust to many of the people he attributes this characteristic to. But there are people that Holden does like other than Pheobe and Allie. James Castle, Jane Gallager, the two nuns......

To Catch a Thief Movie Review

...“It takes a thief to catch a thief.” Well, that’s the saying we’ve always heard. In modern day times, we’ve seen it in productions like Fast and Furious, Criminal Minds, and even in comedies like 22 Jump Street. Hitchcock based his movie, To Catch a Thief, solely based on this saying. John Robie (the infamous jewel thief from previous years) is being framed as stealing multiple precious jewels around the city. The culprit has the same technique and does it with the same stealth as Robie did. The police think Robie could be the only one to commit these crimes so he conjures up the idea that he has to catch the actual thief to prove his innocence. In his struggle to do so, he comes into contact with an old friend (Danielle), a jewel insurer, and two ladies from America (a mother and daughter), all who help contribute to the smooth transitions between scenes and an exciting ending. Therefore, To Catch a Thief is a striking movie, being both witty and suspenseful; Alfred Hitchcock creates this feeling by making the movie not too predictable, scripting engaging characters, and keeping scenes implicit. First off, Hancock set up the movie to where it wasn’t obvious who the jewel thief was, but if you paid attention to detail, you could make a good guess. From the way characters talked, it was believed that a man was the thief. For Robie even says, “He picks perfect victims and only the right stones. Goes up walls, over the roofs, down through the skylights. Leaves no clue and......

The concept is simple: the decision makers within the company should act in the interests of the company, and not in their own interests. The easiest way to comply with this duty is not to engage in transactions that involve a conflict of interest. We often call these "self-dealing" transactions. The concept is that the directors are dealing with themselves, and may not reach an agreement that is fair to the company. An alternative, that is accepted in most countries because a flat ban on self-dealing transactions can be impractical, especially for smaller firms, is to have 2 self-dealing transactions approved by a noninterested decision maker. That decision maker can be noninterested directors, noninterested shareholders, or sometimes both. In the United States, if a conflict-of-interest transaction is negotiated and approved by the noninterested directors, in a......
