People have died of a five mile an hour soft ball hitting them in the exact wrong case. Necks have been broken by falling as little as four feet. You cannot guaratee the man woyuld be alive. There is the chance it had been a serial rapist/killer. Punching one of those is quick way to be added to the list of victims.
Well, i am glad you are happy you live there. And i fervently hope that you never come to rue that very happiness some day. Still does not change the fact that your country has gone from much less criome per capita than the US to the same level. unfortunately ours is dropping and yours rising.....
Oh, I see you ascribe to the theory that only people who have shot is self defense have defended themselves with a gun. I could explain how generally incorrect this is but it would probably be wasted effort. Suffice it to say, that merely carrying a gun is statistically safer than not.
