Those who decry “gun violence” very rarely use the word violence in any kind of rigorous way. That is unfortunate, because if someone tells you “X number of people died last year due to gun violence,” they are including some instances where an intended rape victim shot her attacker, or a policeman shot a meth-head who was trying to stab another officer. They don’t want a well-defined term, because the more deaths you can lump into the statistic, the scarier it sounds, and the greater the urge to “DO SOMETHING,” regardless of whether that something has any likelihood of achieving the stated goal.
No really. Go read it.
