Homelessness is a challenging problem. Some cities have attempted to address it, in part, by prohibiting sleeping or camping in public places. The Supreme Court of the United States is currently considering whether, and under what circumstances, such ordinances are constitutional. I recently listened to the oral arguments in the case. Those who are currently litigating violations of anti-sleeping or anti-camping ordinances may be interested in this summary of the issues, as may those responsible for shaping municipal policy.
