To the chase I don't think it wise to support behaviour that is clearly inappropriate, every citizen has the right to expect proper treatment from the Police if he was causing obstruction he could have been arrested using "Reasonable" behaviour and the concept of "minimum force"
What ive seen is a guy with his hands in his pockets back to the officers being violently struck to the ground nothing to do with what he eats ,drinks or smokes If i had seen one of my guys doing that he would be dismissed at once regardless of the outcome .
