No, of course not. As I have said, ALL such incidents must be investigated as crimes. But imprisoning the surviving victim for defending himself, even lethally, is not the answer, either.
What is considered an "offensive" weapon? A knife? What about a sword? Or a cricket bat?In fact, it is against the law to carry any offensive weapon in public.
And yet, by your own admission the crime rate in the UK is higher than here in the US. And some things I've read suggest that the incidence of gun crimes in the UK have been rising steadily since the gun ban went into effect. Can you confirm or deny this?OK, we might get hit with a bat, or knifed, but we perceive the danger is far less here than American scaremongers such as the NRA whine about over there.
