If every time there's a story about a cop, a bunch of folks come streaming out of the woodwork complaining about the coming police state, people will stop listening.
This is especially true is the complaints are vague, overstated, and irrelevant.
The guy disobeyed a legal order, reacted violently to a legal touch. He got tased. There is no brutality here, just good appropriate policing.
Another thing which gets in the way of your alarms being believed is that you and binnewhaatevershow no real understanding of policing. You try it, do some ride-alongs, realize that a badge is a good target for a bogey to aim at, live and deal with not knowing when a guy approaches you with a frown on his face whether he's going to ask for directions or pull a knife and attack you, with knowing that you don't know and that you may find out too late to prevent getting hurt or killed.
And as for biinejerk's "poor little police man - did he get his feelings hurt?" I am no longer a cop. If you want to say that to me face to face without hiding behind your computer, freepmail me, and I'll set up the meeting. Now that I'm no longer wearing a badge, I'll be happy to comp you some brutality as an amateur.
But to tell you the truth, I'd prefer to see you do what police do and then think about the nonsense you've been spouting.
