That's another symptom of America's lack of the social contract. If the persons who are charged with governing had any semblance of respect for the human dignity, they not only would build public toilets, but also centres staffed with social workers where the addicted have a place away from the public to inject and where the syringes are safely deposed of. It's called harm prevention and this is cheaper (both in monetary and human capital) than just ignoring the problems.
