To this point, there have been at least a few stories of elderly people being beaten on San Francisco public transit for politely asking people to turn their music down.

OK, I read about someone being murdered by their spouse. That doesn't mean it is going to happen to me. The media reports on sensational stories. That doesn't make them normal.

		You tend to know your spouse, you don't know the mental state of people on the train. Especially people who have already demonstrated they don't care about social norms or preserving tranquility in public spaces.
