>Wrong. The posted graphic proves the opposite.
Missed this one.
Your graphic shows 137 total mass shootings over 40 years.
That's not even 20% of what GVA reports for just 2022. You just proved that cherry picking data sets can sometimes give you the result you want.

And again, you're trying to make an argument based on a tiny, tiny, tiny, tiny fraction of actual gun violence.
Change the laws and there will be an average of 3.5 less mass shootings per year.
Based on statistas methodology,
https://www.statista.com/statistics/811504/mass-shooting-victims-in-the-united-states-by-fatalities-and-injuries/there were 1095 mass shooting victims over the last 40 years. So, let's just make the entirely inaccurate assumption that all of these people were killed with "Military style assault rifles".
Let's also be super fair to the data set and only consider the last 10 years. 635 deaths, an average of 63.5 per year..
Even if we totally stop "mass shootings" by "banning ARs", that is only 0.36% of all firearms deaths.
In 2022 the number of mass shooting deaths was 74, so, 0.4% of all firearms deaths.
You're going to have to do better than that. Mass shootings are bad, yes, but you don't make laws that will affect at least 40% of the US population - (and frankly, will increase gun violence see : Mexico ) based on 0.4% of incidents.
