Ok I've had a read over this thread and I don't think anyone has said it but........this "Armed Guards" on busses thing, I maybe wrong but surely that actually puts a loaded gun in the mix?
Whats to stop someone getting his gun and going on a rampage?
Like sky marshals except it's a lot easier to step on a bus in the street than get on a plane.
A knife in your pocket, step onto bus, dissarm guard by stabbing him, grab gun, shoot people.
So not only do you have the threat of terrorists and bombs, but also random hijackings and shootings with supplied weapons.
Of course I could be wrong but thats how I see it.
