12 yr old kids are not of any mental capacity to be responsible for their actions/beliefs....but they are if anything more dangerous than your typical terrorist...They,coming into thier pubescent years can only think of those 76 virgins and rivers of milk and honey awaiting them in heaven once they gloriously blow themselves up.
The kids should be held but not at a prison with adult terrorist suspects...If they had spent three years at a youth rehabilitation/detention centre,they might be far less a threat when/if they are released.
Their current treatment has made them a far more dangerous threat if they are ever released(read next election).
It's too late for them though,might as well execute them....Another example of how Bush doesn't put a value on human life.
