I just cannot even imagine something like that happening. What makes someone do such a horrible thing? And especially when there were children on board? Such a senseless act. How scared those individuals and the victim must have been when that was happening. It is a good thing that that guy was there to help the passengers get off the bus. A tragic event would have been even more tragic had he not been there to save those people. I feel bad because those individuals (including the guy who saved the passengers) are all now scarred for life and their lives will never be the same. Their lives have been turned upside down because of someone else's senseless act and are forever traumatized by it. I hope those victims get the support they need and I hope that the driver's family receives support
