This seems a bit overkill to me. This inmate was under investigation and was talking to the judge about it. Then, it seems the deputy got a little jumpy and the inmate partially turned around. The officer then slammed him into the wall.
This guy is like Jackie Chan! Simple making his phone call and then realizes he can fit through an opening in the window. He makes a break for it and is out the front door. Good effort on the part of the corrections officer for getting through the window also.
After this guy's 15 year sentence is up and he has to serve an additional 6 months, I wonder if he'll have any regrets for punching his lawyer in the face. I would assume after 15 years, it wont be a big deal, I'm sure he'll be back in no time anyway.
