A human response question

The first rule of self defense is run if you can. It's even more true when you are caught unaware like that situation, nobody saw it coming.

I read a lot of the same things the OP did and it was pretty silly, trying to take a knife from somebody is hard to do. Trying to take him in a bus where there's no room to move and no advantage to be gained is insane. Those people are going to have to live with the results of their choice for the rest of their lives but they made the right one.
