Given what we know (unless you just happen to be a total apologist libtard) by what we can see in the video we have, the assailant got exactly what he deserved.
If it turns out to be something along the lines of the assailant was "insulted" due to his "culture" too bad. That is no reason to do what he did. As Mike Katz once said :
"You see, you can beat a dog and it's going to do one of two things. It's gonna roll over and die or it's going to bite you and attack you."
I can only comment upon that which is known by that which I have seen. The antagonist beat the wrong pooch.
