We have a crazy man who should never have had access to deadly weapons. He was motivated by an irrational animosity towards Republicans, it seems. That's this week's target. It could as easily have been Muslims, or Christians, or gays, or women, or co-workers (as just happened in San Francisco within the last few hours), or people of colour, or just innocent Americans going about their daily lives. The targetted groups are endless.

The common denominator is an inability to control access to guns in a way that adequately protects the American people.
