kidnapping requires you move your captive to another location without consent doesn't it?
I think that depends on the state.
Recently near where I live there was a false imprisonment suit against a man who prevented another person from driving away from a crime scene by blocking his car in a parking space. This is more or less how it went down from what I remember.
Apparently the assailant got into a fight with somebody at a parking lot of a 7-11 and beat the shit out of someone. Then he attempted to flea, but a witness pulled their car behind the assailants car preventing him from backing out of the space. The police came, arrested the man for assault and battery, and a month later the guy who prevented his escape was sued for false imprisonment.
Right, he was sued for false imprisonment, not prosecuted. If the government had wanted to prosecute him (although i can't imagine why), they'd have to charge him with...um, something related to obstructing the roadway, maybe? I'm willing to bet that the criminal lost the lawsuit.
Don't worry citizen, the pre-crime division is on its way.
What, do you think that the government should only be allowed to step in after the crime is already committed?
