The Portland Occupation stumbled upon a tactical innovation regarding occupying public spaces. This evolution in tactics was spontaneous, and went unreported in the media. On December 3rd, we took a park and were driven out of it by riot police; that much made the news. What the media didn’t report is that we re-took the park later that same evening, and the police realized that it would be senseless to attempt to clear it again, so they packed up their military weaponry and left. Occupy Portland has developed a tactic to keep a park when the police decide to enforce an eviction.
The tactical evolution that evolved relies on two military tactics that are thousands of years old- the tactical superiority of light infantry over heavy infantry, and the tactical superiority of the retreat over the advance.
