SURREY, B.C. -- Protesters were left frustrated on Saturday after a rally they had planned weeks in advance was shut down at the last minute by police officers. “It’s very frustrating to see the RCMP denied the people’s right to protest today,” said attendee Harjat Grewal. The drive-in rally was to take place at the Cloverdale Recreation Centre on Saturday afternoon. Hundreds also drove into the parking lot at the same location last month in a similar display before convoying to downtown Vancouver. This time, police officers arrived well before the protest was scheduled to start and told everyone that arrived to turn around.
