Terrorists do exist in the us. We usually shoot them before it gets too far, unless it's in a gun free zone. Then they get their body count like you see in Europe.
That’s right. The situation would have been better if every single person on crowded Westminster bridge had a gun. It would have improved the situation to have shots going off everywhere amongst the crowds of tourists and school kids. In such a chaotic situation, even a well-intentioned bystander might accidentally shoot innocent people. Instead, we had a fanatic who emerged from his car with knives- clearly he was unable to obtain a gun- who was shot by armed police who are specially trained for this.
You can’t make it easier for Random Civilian Good Guys to get a gun without also making it easier for the Bad Guys to get them. Maybe that’s how you prefer to do it in the US, but we like our strict gun control laws here. We prefer that the ‘good guys’ who have guns in our country be confined to the police and the military. And I do believe in many US terrorist shootings, for some reason, it’s also usually the police who finally stop the suspects, not a bystander with a gun.
It’s all and well to focus on terrorism, but the US continues to have a much higher homicide rate than the rest of the developed world. And the vast majority of it is from firearms. Even if you factored in our terrorist attacks, we don’t even come anywhere near the homicide rates in the US. If you want to talk about to us about body counts, maybe take a second look at your country before you dispense your advice about how we do things.
