Remove guns, and the crazies will still research some method of creating some weapon online like a pressure cooker bomb and still do damage. So removing guns is not the solution. I think the bigger problem is the government claiming that removing guns will be a solution, you get my drift? USA is such a...deep state kinda country, I definitely support the right for Americans to have weapons, even though I'm not a US citizen or live in America, because otherwise the deep state will completely....you know.
But then what is the solution to stopping people from shooting innocent kids? Tough question. Why does it happen so often in the USA and not in other countries? I think part of the reason might be the way the media covers it in the USA, it gives the spotlight to the criminal and thus future criminals want that spotlight and choose the same path. The crime should be ignored and the police should act and sweep the matter off. That is my solution. No attention whatsoever.
