Possible Solution to shootings:"National Law that requires special training to own any kind of gun."

[SCantiGOP]

2. Simple rule:

Same restrictions as cars.
Must be of age, have had training, and passed testing to get a license.
Then, registration and insurance are required. Any major violation or enough minor violations and you can lose your right to own a gun for a period of time (similar to speeding tickets) or go to jail (similar to DUI).

The NRA will argue that guns are a right, not a privilege; sane people will argue that not being murdered is also a right and there is no burden to treating guns like cars.
