One of the single greatest reasons I intend to move to New Hampshire is this: A few guys (some openly carrying guns) take chalk and write polite but firm anti-cop messages all over the sidewalk in front of the police station. Instead of coming out, beating, and arresting these men, a solitary officer comes out for a nice lunch-break chat about how government is an unnecessary evil.
In many other places around the country, as mentioned in the video below, people would be executed on the spot simply for having a gun, let alone writing chalk messages in front of a police station.
Like Cantwell, I believe that if someone, anyone is attempting to rob, murder, or coerce you, you have an obligation to stop them at any cost. However, if someone is dressed like a criminal but not attempting to commit a crime against you, then you have an obligation to at least give them a chance. This video demonstrates this second situation perfectly.
