Do you think advanced countries are dumb for providing social services, definitely not! As long as an individual has an acceptable living standard he is unlikely going to engage in those activities. A gun is just going to aggravate and would NEVER solve the issue. Lets say guns are made legal, a kidnapper would more likely possess a gun than the victim, then that increases the chance of the victim getting killed. Domestic violence has a lot to do with emotions and, we all know emotions and guns are two ends of a sword that should never meet. Plus domestic violence is also largely caused by inability to adequately provide for family needs.
