How should we address violent crime?

In a recent online discussion, I was asked... “What possible solution(s) do you think would work to help solve the problems of gun violence in America? ” First of all, I want to solve the problem of violent crime, not just "violent crime with guns", so my answers will be directed towards things I think will help in both of those areas. 1) Based on the historical results of “shall issue” programs, we have seen that more people with carry permits would reduce violent crime. 2) Based on the repeated failures of “gun free zones” as a safety measure, allowing carry permit holders to carry in more places would also reduce violent crime. 3) There have been several high profile failures of the background check system to deny firearms sales to people whose mental health issues should have prevented them from being able to purchase firearms (VA Tech shooter, Ft Hood shooter, and the Aurora CO shooter come to mind). There is an obvious problem when mental health privacy laws prevent people from being entered into the ATF/FBI database as they are supposed to be. This needs to be addressed. 4) All states should be required to recognize carry permits issued in other states, just as they are required to recognize things like marriage licenses from other states. 5) Since many anti-gun laws are passed in moments of hysteria, when people caught up in irrational fear are being flim-flammed by media and politicians who lie and misrepresent facts about firearms, to capitalize on the ignorance of the American people, firearms safety training (such as programs developed by the world’s leading firearms safety training organization, the NRA) should be required in all public and publicly funded K-12 schools, colleges, and universities, just as drug and sex education are already required. 6) Cleaning up and consolidating the over 20,000 different, often conflicting firearms laws in this country would make it possible for citizens and law enforcement to focus on “male in se” types of firearms crimes, rather than worrying about “male prohibita” infractions. There should be no more than 10 federal laws regulating firearms and/or ammunition, and each state or territory should not be allowed more than an additional 10;
