Comparative Bullet Lead Analysis Some of the close to likely evidence that is presented in criminal cases comes from the FBI crime interrogation laboratoryoratory in Quantico, Va.

While quieten working at the FBI, metallurgist William Tobin began sceptical this practice.

Tobin says the Quantico lab was the only place in the country that did bullet lead analysis, and the trust that you could actually match a bullet fragment to a specific batch or box of bullets went unchallenged for 40 years until Tobin retired and decided to do his own study, discovering that the basic predate had never a ctually been scientifically tested. In 2002! , confronted with Tobins study, the FBI lab asked the topic Academy of Sciences to conduct an self-employed person review of comparative degree bullet lead analysis. The National Research Council came out with a report calling into interview years of FBI testimony. It found the assume the FBI used for interpreting results was profoundly flawed and that the conclusion that bullet fragments could be matched to a box of ammunition so...If you want to scramble a full essay, state it on our website: OrderCustomPaper.com
