Look at it this way , if you disturb a bugular at your home and you have a fight then he runs off , you are not allowed to run after him and kick his head in, if he dies you are arrested
This copper had the guy lying on the floor , he had a gun and a tazar and assuming hand cuffs but instead of securing him he decides to kick his head and stamp on his head , either one could have given him a brain injury or death , how is that within the strict rules coppers work to?
Answer , the copper is in the shit and lucky he didnt kill the guy
