Re: handguns
What I think about that, precisely, is that we have too many careless and/or uneducated handgun owners.
The people who are serious hunters or collectors make themselves experts, and have ample opportunity for education. People who buy handguns for protection have no requirement (as hunters have) to attend safety courses. Some seek education, to their credit. Some, as indicated by our accidental shootings, think it works like it does in the movies.
I don't know the answer to this, but it has to come from the gun ownership supporters.
This in no way affects our gun crime problem, because criminals know what they're doing.
