love all the internet heroes who would have jumped in to save him
The kid didn't have a chance, before anyone realized what was going on he had probably been stabbed 15 or 20 times, was no hope in saving him. Getting off the bus and basically locking him in there was the right thing to do.
However I don't understand the RCMP letting him stay on the bus so long and taunting them with the head in his hands.
