Trooper vs. paramedic scuffle

http://abcnews.go.com/video/playerIndex?id=7845333

I cant stand cops power tripping they cant hear the patient screaming?,the paramedic didn't do any thing to warrant the trooper to put his hands on him and being rude.Ambulance light on or not,that doesn't warrant the cops to tailgate and cutting off the ambulance,the trooper doesn't have a leg to stand on i don't care what his attorney says.This CNN doesn't give enough context so here's a link to ABC news link to the video.
