Debunking Myths to Forensic Science,[object Object],-Joulyn V Kenny,[object Object],Forensic Expert,[object Object]
In real life, the criminal justice system operates under constraints of time, manpower and priorities. ,[object Object],So what's all the huff-puff about CSI/CID or Mr&MrsMishra.. We should avoid.. ,[object Object]
Modern Television 2 Blame?,[object Object]
CSI Myths: The Shaky Science Behind Forensics,[object Object],Forensic science was not developed by scientists. It was mostly created by cops, who were guided by little more than common sense. And as hundreds of criminal cases begin to unravel, many established forensic practices are coming under fire. By Brad Reagan,[object Object]
Myth no1: The fully equipped crime lab,[object Object],Forensic labs in TV are always fully equipped with the most up to date technology,[object Object],Even the labs with the largest budgets cannot afford to have the same lab quality as the labs on TV dramas,[object Object],Shortages occur with building space, funds, equipment and proficient personnel,[object Object]
Myth no2: One person can examine all types of evidence,[object Object],There are few ‘generalists’ in today’s forensics field.,[object Object],The expertise required for each section of forensics sometimes requires one piece of evidence to be examined by more than one individual,[object Object],The evidence at hand needs to be examined sometimes in different departments of the laboratory,[object Object]
Myth no3: The laboratory personnel examines evidence as soon as it arrives,[object Object],Heard of COC, the procedures that follow…,[object Object],Usually it takes months before time permits an examination of the evidence due to back logs and quality control procedures,[object Object],Positive and Negative Controls have to be taken into consideration before starting an examination ,[object Object]
Myth no 4:Fingerprints susceptible to testing and identification are always found,[object Object],Finding identifiable fingerprints that can be collected and are of a high enough quality to do an automated search are rare,[object Object],Normally fingerprint comparison must be done by ‘hand’,[object Object],The on-demand fingerprint scan(Eagle Eye- The movie in which a burnt body fingerprint had a match) is rare to use and hard to get results from.,[object Object]
Myth no5: Testing for drugs and chemicals in blood is quick and easy,[object Object],The chemical goes in and a paper print with determined results are out….Not Really!!,[object Object],Numerous drugs, botanicals, chemicals that can be presented at any given crime scene and many instruments cant identify them,[object Object],Process often takes weeks or months to complete,[object Object],This also depends on what state the blood is in- wet blood, dried, from decomposed or skeletal remains,[object Object]
Myth No 6:The cooperative crime scene,[object Object],Then we would not have the “Perfect Murder”,[object Object],The ‘perfect’ evidence is rarely there,[object Object],Technology has greatly improved evidence collection but no technological advancements can find nonexistent evidence,[object Object],The discovery of the crime and the time elapsed is the biggest factor,[object Object],And an uncontrolled crime scene(Best Example- Aarushi Murder 2008) is something one should accept if forensic guidelines are not followed,[object Object]
Myth no 7: Use and availability of some sensors,[object Object],Sensors have become a fad trying to convince people of its “hi-tech” use.,[object Object],Some of the sensors used are actually prototypes still in the developmental stages and are not on the market yet,[object Object],The accuracy and power of some sensors has been enhanced beyond what they are currently capable of detecting,[object Object]
References,[object Object],The “CSI” Effect on the Psychology of Jurors:  The Challenges that Pop Culture is Bringing to the Courtroom James McGrath, JD, MPH,[object Object],CSI Myths: The Shaky Science Behind Forensics,[object Object],CSI Effect-Myths and Realities of “Forensic” TV- http://stlcin.missouri.org/newsletters/articles.cfm?ArticleId=372&NewsletterId=37,[object Object]
