I am sorry Pastor, in a real brawl a kick to the head is mandatory. In some instances it is you or them, in those cases it is better to be giving than receiving.
This would probably more accurately be described as what is known as “curb stomping”.
I’m venturing a guess, but I’d say that Kernich was probably in no position to defend himself, nor that he was even conscious when the death blow was delivered.
These people are animals!
