Arrest the alleged felon who is clearly a police officer behind the barricade throwing a device at a disabled man:

This video is looped and then slowed down and it clearly identifies a police officer tossing the device directly at the disabled vet on the ground when the protesters attempt to come to his aid.  It detonates literally right next to him.  None of the protesters are committing any act of violence - they are assisting a men who has just been shot with a rubber round in the head.

THERE IS NO EXCUSE FOR THIS ACT.  EACH ACT OF EACH PARTY STANDS ALONE - NO PROTESTER CHARGED THE FENCES OR OTHERWISE ASSAULTED AN OFFICER.  THIS WAS A PREMEDITATED ASSAULT BY THE POLICE UPON A PRONE AND INJURED MAN AND THOSE ATTEMPTING TO ASSIST HIM.

THE MAN IN QUESTION, A VETERAN, IS CURRENTLY REPORTED TO BE IN CRITICAL CONDITION.

The Police issued the following in response to a question:

Q. Did the Police deploy rubber bullets, flash-bag grenades?
A. No, the loud noises that were heard originated from M-80 explosives thrown at Police by protesters. In addition, Police fired approximately four bean bag rounds at protesters to stop them from throwing dangerous objects at the officer.

It appears that OPD is LYING.  This video, originally shot by KTVU and still available on their web page, clearly shows a police officer throwing the device; it visibly originates from an officer behind the barricade.  If you watch the original you can see the officer tossing the device in the last few seconds of the clip; the Youtube version does not appear to be doctored.  There was no assault upon or any "dangerous object" being thrown at these officers at the time the officer commits his assault.

Honest people, irrespective of whether they agree with the OWS protests or not, must not sit silently and allow this sort of outrageous and unlawful behavior and the resulting blatant lie -- not by protesters, but by the police -- to stand.

The responsible officer(s) must be personally identified, indicted and prosecuted right here and now.  Those who lied in the department about the use of these devices must be removed from their positions for cause without compensation, retirement or severance. 

This department's clear lie means that the remaining assertions -- that the police officers acted only after the protesters first threw rocks and/or bottles -- cannot be accepted as true and this infirmity must stand until a formal retraction is issued.

There are no free lies, especially in matters like this.  Once an agency or person documents through their own actions the willingness to make intentionally false factual statements as proved by conclusive photographic evidence nothing they say can be taken at face value. 

This means the Mayor must go, the police chief must go, and the officer who did this must stand trial, all right here, right now.

Should the people lose what little faith is left in the government and come to an inescapable conclusion that felonious assaults are going to be overlooked "so long as they are committed by police" there is a severe risk of the complete loss of civil order.  Down the road of tolerance of this behavior by the police and city lies chaos.

Nobody with an ounce of common sense wants to see such an event or should be willing to sit idly by while it occurs without vehement protest and every possible attempt to obtain redress by lawful and peaceful means.

Update: I have been emailed by a former military member who states that the device thrown was almost-certainly a tear-gas grenade that exploded (rather than just gassing off); he stated that they are trained never to throw them directly into a crowd for exactly this reason - they do explode rather than "hiss" some of the time, especially if the land on their "cap" on a hard surface.  In addition there is question as to exactly what Scott was shot with originally, so I have reflected that as well.  This doesn't change anything - the victim was clearly shot at close-range in the face with an aimed weapon and the second device was clearly tossed directly at the people attempting to rescue him.
