CSI: Crime Scene Investigation (2000)

Too Tough to Die - S1-E16

Character mistake: Seven minutes into the show, Sarah Sidle is about to do an internal sexual assault exam/kit on an unconscious victim in the hospital, Sarah picks up a metal speculum and says aloud to the victim (in a presumed moment of empathy), that she "never really liked this part of my yearly exam. These things are always freezing" referring to the speculum in her hands. She then brings a speculum to her mouth and begins to blow open-mouthed on it two times, forcing her hot breath on it to warm it. She then begins to insert it into the victim as the scene cuts away. This is pure stupidity, as no trained CSI would ever contaminate the tool like this. Sarah just added her own DNA to the speculum via her breath so any saliva or body fluids are now on the speculum what she is about to use on this patient, who is now also exposed to any STDs from Sarah.

Play with Fire - S3-E22

Question: Why would Catherine take the blame for the lab explosion? If anyone was to blame it was Hodges. Since he accidentally turned on the hot plate and even admits that sometimes it gets switched on by others accidentally, if he had bothered to make sure he didn't switch it on before leaving the room, the explosion never would have happened.
