You are a simpleton if you think that one stops the other. However to answer your question I would take my chances at getting shot by a criminal before letting the police frisk and shoot me because they "thought" i was going for something.
Except that has been the experience in NY. Aggressive policing does in fact reduce crime.
The fact that you trust a criminal more than a police officer speaks to something.
Policing is not regulated to frisking. Thats why its called by 2 different names. Indeed the fact I feel my chances are better with a criminal than a cop speaks volumes.
