Scientists in Israel have demonstrated that it is possible to fabricate DNA evidence, undermining the credibility of what has been considered the gold standard of proof in criminal cases.

Every “CSI” storyline just became suspect.

Or go into a peep show...take a new hankie and wipe it all over the floor....then drop it at the scene of the crime...ewww

It goes without saying but, pick it up with tongs, place inside plastic ziplock bag, throw away the tongs.

Of course this would have the problem that several DNA profiles on the hankie would likely match known local felons...causing untold mischief and hilarity when they were all dragged in to explain. ;-)

"Sure, anyone with unfettered access to a blood centrifuge, and the equipment, knowledge, and skills to perform genome amplification, then cut the snippets to the exact amount, and mix them to a scientifically perfect degree."

Yup. I was in my garage Sunday tinkering with some DNA while I changed the oil in my car and worked on my chainsaw, all the guys around here do it.

Yes he did. But it’s been known since even before that. The secret service always destroys any glasses, dishware and silverware that the President and Vice President use out in the public since at least the Clinton years.

You guys finally get some rain and you go crazy.

Kits to create fake fingerprint imprints have been available for a long time. With some kits you end up with a rubber glove that you wear...you moisten it with an oily little rag that comes with the kit and can leave all the prints you like.

I want John Dillinger's fingerprints!

They're in the Smithsonian.

I'm certainly no authority on the subject, but I believe that "peep shows" went extinct some time ago. They were replaced with a far more efficient porno delivery system - the internet.
