Character mistake: Elliot Stabler is interrogating a suspect and he says "Well maybe he got pissy because of the 2.2 you blew into the breathalyzer." He said two-point-two but he meant point-two-two because a 2.2 BAC is like 5 times the lethal limit, so a 0 .22 BAC makes more sense. (00:20:10)
Smoking Gun - S1-E2
Character mistake: When the bad guys put the generator in front of the air vent, Nigel looks at the white smoke and pointing at it says "Carbon monoxide." Carbon monoxide is colorless, white smoke is mostly condensed vapor. (00:35:20)
