I hate to be "that guy" (ok, well sometimes I like it) -- but isn't there a risk of making one locality much more welcoming to the homeless that we end up being the drop-off point for every homeless person in the region?

My point is not that we shouldn't offer help, but that by doing so on a city-by-city basis, with no overall plan or obligation, we allow many localities to freeload off the good will of the few that try to do the right thing.
