And you don't think requiring licensure won't be abused to disenfranchise minorities and the lower class? There is a reason poll taxes and anything beyond simple registration was ruled unconstitutional for voting, and even simple registration gets badly abused. Any enumerated right cannot have hoops to jump through to actually be rights instead of privileges.

Training is great, and should be part of our compulsory education starting from elementary school due to the fact that there are more guns than people in this country. Free training should also be offered for adults to be able to regularly (annually or more often) attend, and needs to be available so people who cannot take time off work can attend. I think this might be something that the Guard and Reserves might be tapped for, subsidized training.

Keep up and beef up the universal background checks, and they need to be made free and fast so private sales can also use them.

Mental healthcare needs a huge bump, and honestly we need a universal healthcare system because of the disaster our insurance industry has become. Healthcare at this point should basically be a right, and a universal system is the way to go at this point. Trust busting and anti-competition laws need to be enforced to fix the monopoly and oligarchy situations we have causing mass wealth inequality and killing free market capitalism. With better economic conditions and mental healthcare, that will do the most to improve violence.
