Heh, I think Dumbles is about to find out about "Peace Through Superior Firepower" and I daresay he won't like the lessoning. It will be interesting to see just what weaponry strikes the North Tower. I do think Dumbledore acted without thinking, if he'd thought hard about it, he might have realized that he really no longer knew what Harry was capable of. 'Tch, overconfidence will bite you every time.
