No, I wouldn’t as long as the shooting was justified. If I chased him for a mile and gunned him down, then no. And if I shoot, he isn’t getting up anyway lol.
Its a myth UK people cant defend themselves, family or property. I know from personal experience (2008) its a myth, as I defended my home from a burglar. Its legal (as happened in 2012 in Manchester) to kill an attacker/burglar if within acceptable limits of self defence.
Then why do so many of us on this side of the pond read stories in the Brit press about homeowners charged when they off a perp?
