you think there are so much cold bloded killers out there ?
Europe is not like the US, apart in countrysides few have a gun and almost nobody carries it. When somebody kills somebody else it's a setting of accounts between criminals, a love crime or domestic abuse, sometime an armed robbery but still, you cant do much with a peper spray in those cases. In fact the chances of getting shot in the streets are between 0 and jihadi with kalash.
When a little bully try to steal you phone after school, just yell the louder you can until a grandma somewher yells "shut the fuck up or I'll call the cops". It always works.

This isn't schoolyard paste eating contest though, this is the cold, hard, dangerous world. I'd rather have a pistol to keep them at bay, but I wouldn't be able to, so I'd use pepper spray or a knife. Plus, remember the last time someone said the europeans didn't need guns?

Don't trust niggas that hang this shit from their walls.

why would you want that on your wall?
