I may expect that between a thug and wannabe thug, but the circumstances here are different. You can't give someone a fractured skull and bleeding in the brain without intentional, possibly aggravated assault. I would expect a video of the attack to be nothing short of shocking due to the brutality.
So, what evidence has been presented so far? Based on the little we've seen, I find it highly unlikely that the boy could have done something where such a beating is justified.
Most people seem to condemn the actions here
the actions here as 'heavy handed'. Well, what's done here is far much worse. And even if the kid did 'push the teacher too far', I still want to know exactly he's done. Because in the above instance, one could argue that those people pushed the policemen too far simply by being there.
