Crime had been trending down for years, particularly after Clinton was in office because you finally had both parties willing to be a little tough on it. It started climbing again when we started putting a modifier on justice. DA's don't truly prosecute people in the big cities where crime is most rampant. Give the druggies their marijuana and close off other things. Allow them to grow their own. The drug trade is the biggest driver of violence, not guns. The only places where shootings are a daily occurrence are places where young black males who are involved in pushing the distribution of narcotics live. Dry up their product and the need to kill each other over territory decreases.
Agree or disagree, the right to a firearm is enshrined in the constitution. "Shall not be infringed". A round about way to try and impose an infringement is not going to fly with me. Not when there are plenty of other avenues to address the real issue that nobody wants to touch because they are uncomfortable.
