We have guns in the UK but they are generally owned by crimminals 
Exclusively owned by criminals. Thats to stop us from shooting "loveable rogues" like the armed scrote shot by police that caused the London riots, oh, and that other armed scrote shot by police that caused the riots in Telford in the '90's. And of course Trayvon, who was a sweet kid, and was only in that neighbourhood to do some bob a jobbing for his cub scout pack.
