In all the video I have viewed, 2 stand out. one was a police officer accused of sexual harassment, and the other was a 19yr old store clerk accused of stealing a credit card number. In both cases nether accuser knew they were being video recorded.In both cases the accused were vindicated by the tape, and in the case of the police officer the accused was found guilty of perjury and fined. So cameras can be a good thing, and may save your a$$.
