To me this is just an unfortunate incident that so far indications are that it's not to be related to the Occupy movement. Besides the unfortunate loss of a human life the other unfortunate thing is that the powers that be are going to point to this regardless of it being not being related to the protest itself and use it as an excuse for removing the peaceful demonstrators.

Personally I focus my efforts here in concentrating on the bigger picture of educating to help raise awareness with an ultimate goal to help raise the collective consciousness through education so folks will be better informed to formulate some kind of "personal plan"  that fits their individual lives and circumstances to support the movement in what ever way is meaningful to them as an individual. That is the best possible goal in my view 

There are a plethora of videos on YouTube that depict lots of police brutality but that does not in my eyes serve the goal of peaceful protest or educating or "supporting" the movement.
