Dude at my job was talking about this- said if england allowed guns it would've been stopped, and he couldnt believe everyone just stood there. I said england does allow guns and theres this thing where everyone thinks someone else will help, so no one does, and he looked at me, then looked away and said well if england had concealed carry permits, this couldve been stopped. Smh.
But of course that almost never happens though. Not even in the US where we have load sof guns and would be dirty harry's.
I mean for one, someone still has to have a gun
Then we still have bystander syndrome as already described.
Then we have the fact that, believe it or not, most humans are repelled at the idea of killing. Talking about it all macho before is easy but when faced with the actual thing, most of us balk. (the military does a lot of means to get around this, of course)
Not to mention, if random citizens can have easy access to guns, that means random crazy people can too. And it may not have been just one guy murdered.
The thing is guns play into human nature and how we often deal with horrific things like this.
We second guess, wondering how they could have been avoided.
And we also look for things that will give us security in a frightening world. Even if it's just psychological.
So guns get seen as some kind of super power. They can give us the feeling that we have the power to keep bad things like this from happening, even if we may still be powerless.
I'm sure there's some kind of psychological term for that.
