It did. The source of the problem is in people's hearts and minds, not some pictures or laws. I don't blame the gun for violence either.
OT,
Laws create economic incentives that change behaviors. Let's use your example. Sure guns do not cause crime, but bad laws the prohibit gun ownership and self defense do cause higher crime rates. When criminals know they can take you stuff and there's nothing you can legally do about it, it happens more often. Same with Family court laws.
80% of divorces are filed by women. In general, it's not men that are leaving marriage, it's women. Why? A very large factor in all this is how the family court systems made it easy for them to take another persons future earnings and possessions.
