I once had a conversation with a crime scene technician. He confirmed what I’d heard that juries were now starting to almost demand the full blown super high tech CSI treatment for every case. This is absolutely impossible. Most of the stuff they did on CSI was legitimate, but he told me there’s not one crime lab in the country as well equipped as the TV show. And of course, the time requirement is greatly reduced.
There is no possible way to devote total resources to one crime, especially not something as basic as a stolen car.
You are 100% correct and then add in the cost. Equipment that needs to be updated all the time and highly trained personnel cost money.
A trial that took place in Atlanta, some years ago, had some forensic evidence. At the opening of the trial, the judge told the jury, believe it or not, that what they’re about see and hear is not TV. And that if they wanted a TV crime lab, their property taxes would go through the roof, for one, and that DNA results aren’t completed in 20 mins.
