My perspective on the whole issue is likely significantly different than the average massageplanetite.
Ultimately, my opinion on the subject boils down to "Two wrongs don't make a right." I will not deny that the US government has done some Bad Things. However, I can't necessarily agree that leaking classified documents into the open is an appropriate remedy. As I indicated above, I think that more harm than good will come of this as governments (US for now, but who knows what government will have Gb of data stolen next) ratchet up the security measures and mount aggressive witch-hunts.
This will not help the DATD repeal crowd for example. Given that Pfc Manning, accused of passing documents to Wikileaks, is openly gay, his decision to illegally release classified data will only serve as ammunition to conservative elements in the US military who see homosexuals as unreliable and untrustworthy.
