I'm not trying to, erm, 'apesh*t on your ass'. I'm bringing up a valid point.
Forgive me for asking, but why are you even here? This is a forum about immigration. You said you wanted our opinions but when you give them you're aggressively trying to shoot them down with failed logic. What gives?
In regards to being in serious danger of arm or being killed, we have a right to defend ourselves in the UK as well, provided it is not excessive. If you kill someone who is trying to mug you, for example. That is generally frowned upon. I don't have much sympathy for the mugger in that example, but those're the laws you work with. This is probably a debate best reserved for a forum about laws in the UK and the criminal justice system, not one about immigration.
