I can't agree more. Simply put, even if you do manage to get a thumb up from the Sheriff in California for a permit, the fees really are a tax on the poor as well.
That depends on what you define as a "mass shooting". Some of the statistics turn out to be playing a game of sleight of hand, defining events that really shouldn't be classified as a mass shooting as a mass shooting. Most of that talk is to get the peanut gallery up in a tizzy about a problem that is far less dire than suggested.
Here's a link to some data being combed from 2019.
Frankly, I think we could stand to increase education around the issue of guns, mental health, and personal responsibility, rather than trying to reflexively legislate away access to firearms, which primarily affects law abiding citizens and not criminals.
Also all gun laws are discriminatory toward the poor and minorities disproportionately.
