lol, willy! guess england hasn't heard about that rule!
''Knife violence is a big problem in England, yet British police have fatally shot only one person wielding a knife since 2008 – a hostage-taker. By comparison, my calculations based on data compiled by fatalencounters.org and the Washington Post show that US police have fatally shot more than 575 people allegedly wielding blades and other such weapons just in the years since 2013.''
Why do American cops kill so many compared to European cops?
Can't speak for England but this 21 foot rule is fact and has been proven time and again, look at the videos and see for yourself.
After they took all the guns in England the number of home invasions went through the roof, no danger of the crooks getting shot by the homeowners. See my sig line.
Guess we just disagree, and that's OK.
