I guess I also have to add that anyone who believes everything that is on tv (or thinks they understand something because they watch a prime time tv program) is the problem in this situation.
Those of us who have actually studied this (somewhat), understand that yes, DNA takes a hell of a lot longer than a few hours and that real CI's don't do much more than collect evidence. But how interesting would this show be if everyone just did their one job?
I've always wanted to go into forensic pathology but as luck would have it, I chickened out in college and refused to take the
natural science classes...out of all the crap I'd have to take in grad and medical school, I didn't want to take undergrad natural science.
