Arrested for blowing bubbles at the G20 in Toronto?

This video shows a police officer at the G20 protests in Toronto threatening to arrest a protestor for blowing soap bubbles ("If one of those bubbles touches me, it's assault") and then leading the protestor away, presumably for the aforementioned "offense." If the goal of the police at the G20 was to act pissy and escalate minor incidents into major ones in order to assert their authority, mission accomplished. If, on the other hand, their mission was to de-escalate, keep the peace, find rapport, and celebrate the democratic right to protest, this officer is an abject, total failure.

G20 Policing: From Bubbles to Bookings?
