In this clip from the TV show Cheaters, a private security guard uses a TASER on a man caught cheating on his wife. During the confrontation the man argues with the parking lot private security guard. The guard shoots the man. His wife does not know what happened to him. The Cheaters detective threatens him with another shot.
Here is an example of how technology designed for law enforcement purposes is not only abused by the police, but also by private persons who are not as strictly trained. Usually when the police use a TASER the victim is examined by an EMT or brought to a hospital. In this case the man just drives off.
