1—The reason for the UK’s high figure have been discussed here many times. Its the high number of violent offences on the statute books (28) that cause the figures to be so high. Many UK crimes of violence arent classed as such in other countries.
2—True, but then I am in Scotland. LOL.
3—Very true.
And while we're explaining things, a significant portion of the part of violent crime that is much higher in the US, criminal homicide, is attributable to the Mexican/S American drug trade, and where that hits the streets with inner-city drug gangs.
Much of that is confined to active participants in that industry, and is relatively invisible to law-abiding citizens.
I have a suggestion, sir: stay in Scotland. Live in your fantasy world and hope like hell that none of your UK "youts" don't beat the crap out of you. I'll live here in the dreaded USA and take a chance that I can use a firearm to stop any thugs that intend to do harm to me. Too bad about you.
