I don't want to read anything into this that wasn't intended but are you saying that society should be harder (crack down) on homeless people but not on other disadvantaged people?
I'm saying that it can't just do that even if some people want exactly that. Personally I feel the optimal solution is a nation wide social support program but that will never happen in the US. Beyond that I'm as stumped as everyone else.
Homeless camps are unsanitary which leads to horrible diseases; Drew Pinsky is trying to get action by screaming about typhoid fever and the plague. Its not simply a matter of compassion for the homeless, there is also a public health angle.
