I haven't heard of any recent crazy snippers or school shooting in France.
You can't shoot guns if you don't have any.
The US culture IS strange. You even have this word, 'packing', short for being armed. Having a slang for that is very, very weird from an european point of view.
Hell, here, the worst you get for somebody being mugged is that they used a knife.
Guns are only for the mafias, which is definitly not day to day operation.
Don't get me wrong, i like going to the shooting range. But I woulf not like the content of the club safes to be on the street.
But I agree with one thing. I've been to the US 5 times, and the cops are scary. I have to go next year, and I don't feel confortable at all, even just passing the border.
It's not a good sign for your country.
