Michelle Malkin has two good posts about this, an initial post and a follow up describing in detail how the hack went down--and how they got caught.
The hackers themselves may or may not have had a political agenda--but Gawker certainly does; I hope they throw away the key... for all involved.
(Brought to you by the same ideology that brought you The Lives of Others...)
UPDATE: Glenn Reynolds twists the knife:
THEY TOLD ME THAT IF GEORGE W. BUSH WERE RE-ELECTED, no one's email would be safe from the prying of jackbooted thugs motivated by politics, not national security. And they were right!
I emailed Nick Denton about this, and he replied: "We didn't publish Bristol's phone number. (Tho we did call it. And we did publish shrunk screenshots of the emails.) You know also that we'd have no hesitation in publishing similar info about Obama or Biden. If we're sleazebags, we're equal-opportunity sleazebags." I like Nick, but this was not Gawker's finest hour.
UPDATE: Reader Rahul Banta writes: "Maybe this is why John McCain doesn't use email?!" That would be smart.
