I have my reservations about leaking political or classified information in some cases, because as Wikileaks has demonstrated, leaks can be used to push a political agenda, rather than serve the cause of unbiased truth.
But scientific knowledge benefits the progress of humanity as a whole - the truth doesn't have a political agenda, although it certainly can discredit political axioms. Trying to keep it contained, controlled or limit its access to a select few should be considered a crime against humanity.
