they are unarmed, just like the other cases where this has happened. Surely in acountry where ak's cost 100 bucks we can afford to get a couple of guys on these buses armed. There is no excuse for letting these guys get killed without giving them a chance to fight back. All our police carry firearms everywhere they go just in case they need them. I cant tell you how many times I have heard of an off-duty cop that stopped a robbery, assault etc.
