I am speaking from experience. I have never used "tweezers" in the lab, and never, ever heard them called such. :shrugs:
If the alleged contamination did not occur in the shoebox, they use disposable "tweezers" and pipette tips, where do you think it comes from? Anything else holding material to be tested is also disposable.
What does Dan O mean by a "sterile environment"?
I don't understand why the knife would have been removed from the evidence collection bag and placed in the box and then sent to the forensics lab in Rome. What is the reason it would have been unbagged before it reached the lab?
I understand there is no completely "sterile environment" when collecting evidence and where that evidence comes from, but what is the point of removing it from the collection bag (which minimizes risk of contamination) before it would reach the confines of the lab?
