There is every possibility that the blasts were carried out by muslim guys. But they are not fools to remain as sitting ducks, waiting for the police to come and get them. The police will make scape goat out of old cases as well as new muslim boys, just to pacify the public. Thats what they want POTA for. We have to give the police their means , but they should not misuse them, or else in the bargain they will manufacture more terrorists.
