 Supreme Court decided this week that cities can enforce bans on homeless people sleeping outdoors in West Coast areas where shelter space is lacking. The case is the most significant to come before the high court in decades on this issue and comes as a rising number of people in the U.S. are without a permanent place to live. In a 6-3 decision in the end, the high court reversed a ruling by San Francisco-based appeals court that found outdoor sleeping bans amount to cruel and unusual punishment.
