Robert Marbut, a consultant based in San Antonio, helps cities and counties deal with the problem of homelessness. He says he falls somewhere in the middle in this debate. While he's opposed to criminalization, he thinks "street feeding" programs that distribute food in parks and under bridges can do more harm than good.

"Street feeding is one of the worst things to do, because it keeps people in homeless status," he says. "I think it's very unproductive, very enabling, and it keeps people out of recovery programs."

That is the middle ground?!
