This is basically old news.
Real scholars of opinions who are not motivated to produce results for political reasons have pointed out on guns that:
1. For most of the country (not Mayor Bloomberg), gun control means keeping them from criminals.
2. For most of the country (not Sen. Feinstein), they support the right of law abiding citizens to own guns for self-defense.
There are nuances about weapons type driven by tragedy but the core is what I said - known for a long time.
