More importantly - we could also try to fix the division and culture issues that stirs up the violence, but for separate reasons, no-one wants to do that either. Interestingly we'd rather make people impotent than good.
Too often these "it's not the guns it's X", then use that as an excuse to do nothing rather than focus on solving X. I tend to side with the folks pushing for gun restrictions more because they are actually pushing to try something rather than doing nothing.
