Mayor London Breed said a “very aggressive” sweep of San Francisco homeless encampments will start in August, after a recent Supreme Court ruling cleared the path for widespread enforcement.

In June, the Supreme Court ruled that enforcing rules against homeless people for sleeping outside doesn’t violate the Eighth Amendment’s “cruel and unusual punishment” clause.

On Thursday, Breed celebrated the ruling and said the city plans to change its protocols and may begin issuing criminal penalties against homeless people.

“Thank goodness for the change in the Supreme Court decision,” Breed said at an election debate hosted by a local firefighter’s union. “Effective August, we are going to be very aggressive and assertive in moving encampments, which may even include criminal penalties.”
