Expulsion isn’t impossible, but general practice is to try and keep the student in the school and teach them to do better next time - not just pass the problem on to somebody else knowing that nothing will be done to correct their behaviour at all if that happens - with expulsion only being used with repeat offenders. These may well be repeat offenders but if this is their first serious breach, suspension is most likely.
More than one kick and more than one punch was thrown. They are already repeat offenders. Not only did one of them kick him unprovoked, but the others kicked him repeatedly when he was down. Each of those is a separate criminal attack.
Wow. That is all I have. I imagine these teens/kids/thugs will truly embrace any “correction” the school offers and never be naughty again. Does anyone believe that this is their first offense? Maybe first one where they got caught, but these young men did not start off with beating down a white kid with his hands in his pockets. They have misbehaved before, I am willing to bet. But, it is cool. They will have some free days from school to plan their next bit of fun.
