I’m not real convinced that Chocking is okay.
http://www.inquisitr.com/3195845/texas-man-choked-mugshot/source/obj/, but according to the Harris County Sheriff’s department; it is.
I see at least two officials holding the individual, I can understand assisting someone by holding them up. BUT that would be generally at the wrist or by the back of the head. Such as the official on the right is doing.
The one on the left is clearly chocking him.
