andr3w - cats BURY their waste. it's one of the perks of owning one. what about all that bird sh*t then, and fly droppings? your yard is already full of nature's excrement.
wpdunn, don't talk out your ass. i work in a homeless shelter. while i agree that too many people were put out on the street with no safety net, it is possible to have people committed for their own safety. A fellow was involuntarily committed recently for not treating his tb, which was putting the general population at risk.
the idea of armed panhandlers scares me, though.
