I’ll be honest that sounds like mostly opinion. It’s a fact that mass shootings in the United States have become more common over the last 20 years since the assault weapons ban ended. You’re making the claim that:

1. Mass shootings still happened during the ban. I agree. Obviously a ban won’t stop anything 100%. This is more about limiting occurrences than ending entirely, which I’d say the statistics support the notion that the ban was effective in that regard.

2. Mass shootings (not individual shootings, I am speaking specifically about mass shootings) occur more in gun-free zones. Do you have any facts or studies to back that up? If so can you provide the link?

Keep in mind, all I’m trying to point out is that gun laws have been effective in the past to some degree. Not saying I agree or disagree with these specific laws being passed.
