Why is it that the gun lunatics thinks that someone is somehow wrong headed to be scared of people with guns? The whole point of gunwanking is to wave a gun in people’s face so that the holder can get a stiffie from feeling how powerful they are. And when that sort of behavior stops giving a powerful enough stiffie some of them start killing people.
If someone walked down the street waving a club with spiked nails in the end or a samurai sword I would be just as worried.
If someone wants to behave like a threat, I have no problem with law enforcement using them for target practice.
