I think that may be the case.
Getting attention for the OWS crowd at all costs... maybe there will be more of this the closer we get to the ‘election’.
In any case, nothing justifies murder.
I watched a program on Glenn Beck a fedw months ago and he had sound bites of the OWS people calling for violent revolution. I think this is all part of that. In addition everytime there is one of these events Obama and the left start talkingg about gun control.
