About the only thing we do know for sure is that guns don't cause crimes. Inanimate objects never do. What we can prove is that gun ownership is way up but gun crime didn't increase as the gun grabbers would have liked everyone to believe it would. The steep drop in crime shows that other measures have been very effective at reducing crime, gun control hasn't.
