Well, I think that the liberal supporters of this OWS stuff are turning this into a no win for law enforcement. And I am no cop, but I do believe that law enforcement would say that use of non lethal force such as pepper spray is not only meant to subdue threat, which IMHO surrounding police is a threat, but also to force people to submit without risk of injury. Is it pleasant? Hell no, it isn't supposed to be. But, The dept, has offered that they entered the quad to enforce a no tent rule, and were trying to leave when surrounded, and people sat and locked arms blocking the walkway. When officers told those blocking the walkway, which is clearly seen on video earlier the one officer tells them to clear the sidewalk or they'd be sprayed, and arrested. They refused, and they got what was told was coming. If they would have just cleared the sidewalk, then no one would have even been arrested, or harmed in any way. The protesters provoked this, and IMHO got what they deserved.
