It is disingenuous to conflate "gun violence" with suicide.
>In the event that someone does break in, gun owners are more likely to die than non-gun owners.
I've never heard of this statistic and I suspect that the relevant literature is an interpretation based on questionable assumptions. Do you have a source?
>We are so, so far away from a sane, functioning public safety system in this country it can be depressing.
Allowing responsible gun ownership is neither insane nor an indication of dysfunction. In fact if you remove a single demographic from gun violence statistics, the US becomes one of the top 5 or so safest nations, in spite of the highest rate of gun ownership in the world.
