She's using cars as an example?
Cars require a driving test and a physical fitness test, as well as having strict age limits. Road users have to follow strict laws, including speed limits according to the area.
Sensibly, simply because one has a licence to drive a 5 seater family saloon car does not entitle one to drive a seven ton lorry. The test and conditions for that are far more stringent, and those for a road haulage truck and trailer are even more stringent.
So by all means lets apply similar conditions to gun use. A basic test for using a .22 calibre, single shot, sporting rifle, and then ever more stringent tests for increasingly potent weapons up to truly stringent tests and laws covering the ownership and use of assault weapons.

This person is 100% idiot.
"And we did this not by banning tobacco, but through a consistent and coordinated effort of approaching the public health problem from multiple angles. We launched massive education campaigns, we put warning labels on tobacco cartons, we passed policies (like nonsmoking and smoking areas)"
It was LAWS that used money from tobacco sales and lawsuit settlements that funded education campaigns and put warning labels on packages of tobacco products. And what in the holy fuck does this moron motherfucker think "passed policies" are if not laws?

Funny? Maybe not. It's something States can do and it HAS worked with smoking, etc. I'd support just about anything to make this damned gun violence better...wouldn't you?
