You don't need a gun. Just train up on judo and have 911 handy. Europeans do just fine without guns.
Yeah, Europe looks pretty awesome right about now. Great example.
911 can't help you when shit goes down. Cops come afterwards to outline the dead bodies in chalk and attempt to figure out what happened.
And why do you guys need these?
First of all, nobody really "needs" anything other than oxygen, shelter, water and food. How much shit do you own that you don't really need?
Secondly, in America we aren't required to need something in order to own it. Wanting something is a valid enough.
Third, they do serve several functions like recreational shooting, hunting, home defense and most important they can be a deterrent against government tyranny.
Lastly, go fuck yourself.
