Simple, if you want to prevent another mass shooting stop giving everyone and their grandmother a gun. I have a mental health diagnosis and I can go out and buy a gun in this country, it's ridiculous. Canada has on average three mass shootings a year mostly in the bigger cities. Ottawa had a mass shooting three years ago where Parliament Hill got shot up. Here in the US however there are mass shootings every single day. Why? Because, we let ANYONE go out and buy a gun regardless if they're criminals, mentally ill, or just plain wacko let's give them a gun. There's no gun control in this country at all and then we're shocked when a school gets shot up or a local Walmart gets shot up and then we wonder why. If they didn't let anyone own a gun there would be a lot less shootings. But, we can't do that It's too logical and people would complain because they have to have their precious guns. After all It's one of the amendments to the constitution
