A reader writes:

As a former member of a liberal church in Tennessee, this shooting really hit me hard. And it occurred to me that another strikingly sad fact about the gunman is that he was unskilled, unable to find a job, and his food stamps ran out. In other words, the free market had no place for him, and the social safety net wasn't there to prevent him from decending into total destitution. And who was he angry at? Liberals. The same liberals who say that we need to strengthen the safety net for just such people in just such circumstances. It's a tragedy in a lot of ways.
