RCMP patrolling Mark Carney event, demanding people identify themselves & kicking them out

This is escalating very quickly...

The RCMP are patrolling the Mark Carney event, demanding people identify themselves and kicking them out even if they are invited or registered.

The RCMP also kicked out at a number of independent journalists and denied entry entirely to a number of people.

Why is the RCMP gatekeeping for unelected Mark Carney?

Does this kind of behavior remind you of anything?
