I have to agree. How can a bus load of people allow someone to get beheaded?
Did they all run off of the bus or something, or did they stay on it while this was happening?
I think it's a duty by just being a human being to take action of some sort.
The first rule for rescuers is "protect yourself". Dead people cannot be heroes. Because everyone else left the bus, we have a singular bizarre incident, but only one death. The people who disabled the bus and prevented the beheader from leaving it need to be commended for containing a potentially wider tragedy.
Actually, the attempts being made to limit the issue to "the bus" seem to me to be a bit disingeneous. It is more about people going to the aid of a person being attacked.

p.s. And, though I may be over-working the point, one gun and any rescuers, in this case, would have been well protected.
