I haven't seen the episode (it's not being show till next year in the UK) so won't argue the details. But i've always found CSI to be the opposite of 'dumbing down'. Within the limits of having to make it good television (ok the police procedure is nonsense, CSI's don't interview and DNA results don't come back hours later) it's the last series to insult your intelligence. Some baddies get away. some were never even crimes. the CSI's never use their guns and shootings, even by the cops are presented as the tragedy they are.
But what seems obvious to us isn't to others. And didn't to us one time. Ask around and I bet you'll find plenty of intelligent people who don't know to never leave the vehicle, or travel by day in a desert. You ever wondered why you are the only person at work with a torch and a knife?
Besides didn't someone say she had to bandage her head? Not the best situation to be thinking straight.
