Under a 12-year-old court settlement, police can’t arrest people for sleeping on the streets. That could come to an end. Lawyer Ted Olsen, who successfully argued Bush v. Gore before the Supreme Court, is arguing a case that seeks to make it okay for police to arrest homeless people for loitering. His argument: the encampments are a public health crisis, not only for the surrounding community, but for the people living there. He says the encampments keep people from seeking safer shelter and services.
