Nah, you can't just let every loudmouth who issues you an order in public to intimidate you. I agree America is full of psychopaths compared to civilised countries but Bisping was hardly egging the situation on by not doing what he was told to do by a complete stranger.Never the less, he's there with his family and he's egging on a situation, with someone that very could have a gun on them. He's lucky he didn't wind up pissing off a gang banger that would happily throw thier life away putting a bullet in his skull. There's more than ebough of those people in America. Really bright. Just put the phone away, and walk away from the loud mouth.
I'm no wannabe tough guy and I'm hardly looking for confrontation when I go out in public but If some asshole approached me and told me to stop filming a parade or a band o public property I would similarly tell him to fuck off.
