Black Lives Matter movement members lit up the streets of Seattle on Thursday with chants of 'F@ck the Police' while waving placards. It didn't take long for the police to respond - officers on motorcycles quickly arrived on the scene to supervise the march. Seattle's march was one of many occurring across the United States, in what organisers are calling "A National Day of Protest to Stop Police Brutality, Repression and the Criminalisation of a Generation."
