For those going to a march:

Hug Power

"Hug Power" is a technique that may be practiced in some of the more tolerant areas. It can be very effective in stopping police arrests, but it is a risky tactic that will only work under the right circumstances.

Hug Power is used when you wish to deter and prevent arrests, sometimes even resulting in an "un-arresting" or "de-arresting" of the cannabis criminal out of the hands of the police.

Hug Power is practiced simply by a group of people all hugging the person who is being unfairly arrested. If a large number of people are all holding on tightly to each other, with the intended arrestee in the middle, then the police have to pull off a large number of non-violent protesters to reach their target.

I have used this technique at a number of rallies in Edmonton and Vancouver. We have successfully stopped the police from making their arrest a number of times.

...Hug Power does not mean "hug the police" â?? it means "hug the person getting arrested."

... Hug Power only works on victimless criminals, and only works when video cameras are around to record the unjustifiable use of force by police.

...one is not to touch the police during Hug Power. The point is to obstruct the arrest only. Police should always be spoken to politely, but firmly.

If you are practicing Hug Power, be prepared for the real possibility of getting roughed up or beaten by the cops at some point.

The cops still have "Rodney King-o-phobia" â?? they hate getting caught on film using force without clear justification. So be sure to have plenty of independent cameramen and videographers at all your events! The chance of being caught on film is the best deterrent to police violence and your ultimate victory.
