G-20 arrest was by police force, not military.

The individuals involved in the 9/24/2009 arrest which has appeared online are law enforcement officers from a multi-agency tactical response team assigned to the security operations for the G20.

It is not unusual for tactical team members to wear camouflaged fatigues. The type of fatigues the officers wear designates their unit affiliation. Prior to the arrest, the officers observed this subject vandalizing a local business. Due to the hostile nature of the crowd, officer safety and the safety of the person under arrest, the subject was immediately removed from the area.
