Does anyone think George Zimmerman is guilty of murder?

[imp]

So is an exposed weapon a crime in some states?

Could you walk around like a cop with one on a belt?

I have seen people in Arizona and Montana carrying openly. I understand that it is the same in New Mexico.
You don't see it often. Though in Arizona, just by coincidence, I saw 8-10 people carrying openly, all the same gas station. One of them was an obese woman in a floral print dress, with a gunbelt around her.

Im from the uk and i find this very disturbing. America is a huge place and these gun laws seem to differ from state to state.

Why is there so much variation in this gun culture in each state?

Something like this zimmerman case has never happened over here..how can a country love the gun so much.
