Its hardly cherry picked tbh.. it is blatantly obvious
Picking 'gun murders' or 'shootings' instead of 'murders' and 'woundings' is clearly cherry picking. It completely disregards the fact that the tools don't cause the crime, and is only ever done by people trying to twist reality to suit their irrational desires to ban things.
Not much, if at all but its hardly relevant - hand gun murders were and are still very rare over here - but you're completely missing the point. Having lots of guns present and carried within a society increases the chance of guns being used and therefore people being killed - its that simple.
Except it doesn't, there's no evidence to support this in reality. The number of gun related accidents certainly doesn't warrant banning them ahead of other things (such as domestic swimming pools and horseriding). Overall suicide rates and overall crime rates don't change when you ban guns, or certainly not in a positive manner.
I'm sorry but there isn't a border around Washington DC - banning hand guns in a city inside a country in which they are freely available isn't necessarily going to do much.
Banning handguns in the UK didn't do much either, are you noticing the pattern yet?
Murder rate in DC is over 10 times that of the UK... they already had a massive gun problem before banning/attempting to ban hand guns.
DC has the highest murder rate and the strictest gun control in the USA. It also has a murder rate that bucked the national trend and rose when they banned guns.
Why are you so unwilling to actually acknowledge that guns are a tool, not a cause, of the problems?
