(A) If you discover a shoe print in dry sand, you should place your form around the impression. Then mix your dental stone with water until it has a batter consistency. Then you sprinkle talcum powder over the impression to make it firm. Then you pour your mixture over a spoon or stirring stick to control the direction of flow of the mixture. Then let it sit for 30 minutes or so and then begin to take the cast out by placing a knife about an inch off the cast and stick it deep enough to get under the cast and carefully pry it up.

    In recent years, television shows such as CSI and NCIS have placed science in the spotlight, frequently depicting forensic science as some type of futuristic magic, unravelling crimes within an hour and without error. Of course, these shows are only fiction. One forensic scientist estimated that “40% of the science on CSI does not exist, and most of the rest is performed in ways that crime lab personnel can only dream about” (Winter & York, 2011). With more than 90 million people watching crime-related shows every week, it is not surprising that the effect of their popularity has become evident in the real world, specifically in real-life criminal trials. Science is bow thought of as a method of catching and convicting criminals, and forensic investigators are basically the heroes who are capable of…

    The period of c1886-c1926 saw great changes in investigative methods and thus lead to huge development in policing and how crime was dealt with. Such changes include the creation of the CID, and have shown to have more significance than others. For example, the introduction of forensic science enabled police to convict criminals in multiple cases, such as George Joseph Smith and Dr Crippen, rather than the use of telegram which only showed major significance in the Crippen case. A great flaw in 19th century policing regards the very few investigative methods available to detectives at the time.…

    Evidence from these scenes should be collected by placing them into air-tight bins or containers to help prevent from the evaporation of flammable substances. The glass cases and paint cans would be great because of their airtight lids. Avoid the use of plastic bags because they will produce harmful gases when mixed with these substances. 1.

    Forensic investigation not only aids to the detection of criminals and their prosecution, it is also a huge deterrent for committing a criminal act due to the sophistication and thorough analysis of the smallest amount of DNA. This knowledge is widely publicised through popular drama television shows such as "Crime Scene Investigation". But, since the privatisation of Britons state-run forensics science services in 2012 which was deemed the best in the world, the police have lost a great asset to secure convictions and manage crime. Peachey (2015) reports spending has been cut by £20 million on forensic examinations over the last two years, with the possibility of a miscarriage of justice as there is a reduction in the analysing of DNA samples…

    Forensic psychologists play an important role in the criminal justice system. They must assess whether defendants are fit to stand trial and whether they were sane at the time they committed crimes. In some cases, officials may also ask them to assess the mental health of inmates on death row. Inmates who are insane cannot be put to death.…

I have always been intrigued by the science of pathology and anatomy, the human body holds a multitude of secrets and has endless capabilities.…

    Proper Evidence Collection It is important to properly collect evidence in order to avoid contamination. If the evidence collection is questionable in a courtroom it will be disregarded and can really hurt the case. Any questionable evidence can even be thrown away if the collectors make a wrong move like coughing or sneezing on a q-tip with blood set out to dry. The first step to collecting evidence is wearing gloves.…

    As the rational values of the Enlightenment era increasingly permeated society in the 18th century, criminal investigation became a more evidence-based, rational procedure − the use of torture to force confessions was curtailed, and belief in witchcraft and other powers of the occult largely ceased to influence the court's decisions. Two examples of English forensic science in individual legal proceedings demonstrate the increasing use of logic and procedure in criminal investigations at the time. In 1784, in Lancaster, John Toms was tried and convicted for murdering Edward Culshaw with a pistol. When the dead body of Culshaw was examined, a pistol wad (crushed paper used to secure powder and balls in the muzzle) found in his head wound matched…
