(Portland, OR)  --  The ACLU is suing the city of Portland over the police bureau's move to "kettle" dozens of protesters during a June demonstration.  The organization says police violated protesters rights by holding them inside a city block without food or bathrooms, refusing to let them leave for nearly an hour.  The demonstrators were counter-protesting at a Trump Free Speech Rally when police blocked them in.  The ACLU says police shot pepper bullets at protesters who tried to leave the blocked-in area.  Police also allegedly photographed each counter-protester and jotted down their identifying information before allowing them to leave the area.
