Lozman v. City of Riviera Beach
Right to Protest In Lozman v. City of Riviera Beach, the MacArthur Justice Center stood up for the rights of protesters in an amicus brief, showing that the mere existence of probably cause does not justify an arrest in retaliation for speech. The U.S. Supreme Court agreed, holding 8-1 that at least in some circumstances, probable cause does not excuse a retaliatory arrest.
