You get bomb threats at schools a lot in Australia, mainly from students who want to go home early.
Same with any other schools any where else in the whole world.
I personally think its a decoy for plp who were related with the attacks two weeks ago to make a run for it.
That's a pretty retarded theory...
The policeman said 'mind that hole, that's where the bomb was'. The metal was pushed upwards as if the bomb was underneath the train. They seem to think the bomb was left in a bag, but I don't remember anybody being where the bomb was, or any bag," he said.
Could it be the French? Or Al Kaida?
