Frustration with police simmers in Montreal's north end after riot

Nothing justifies this. There may be a problem with the initial police action (may be -- often what seems problematic at first is totally proper) but even if so there is never ever call to use force against lawful authority. Remember, civil disobedience (which may sometimes be justified) involves non-violence and accepting the arrest and punishment that follows.

MONTREAL - Montreal's mayor is promising to push for a speedy and public investigation into a riot that broke out following a fatal police shooting.

Gerald Tremblay says the only way to return order to the city's troubled north-end neighbourhood is by being up front about what prompted police to open fire on a group of youngsters on Saturday.
