Because the US is the only country in the civilised world that allows its citizens to be slaughtered every day in defence of some bullshit amendment .The rest of the world is safer.
Actually, Americans use that Amendment to stop 2.4 million criminal attacks every single year......and as more Americans owned and carried guns from the 1990s to today....our gun murder rate went down 49%, our gun crime rate went down 75%, and our violent crime rate went down 72%......
While today, the gun crime rate and violent crime rate in Britain are going up....after they banned and confiscated guns....
