How about this: it's my laptop, and I reserve the right to use it to take pictures any time I see fit?
I'm okay with running the picture of the guy, and publishing the data, as long as there's a clear disclaimer that this is just information pulled from your own laptop, not presented as evidence in some kind of criminal proceeding. We do this all the time with videos on the news that show crimes in progress. Heck, we did it with the rioters. Local papers ran big pictures of them on the front page. Simply making public video and data that you have every right to have and use isn't the same as calling the guy a crook and demanding he be hanged.
Now yes, the mob will probably take over from there, but that's because the net is full of mobs, not because you've somehow made a mistake in publishing the data. I am very concerned about folks taking justice into their own hands, but I don't think that my concern somehow changes the right of this guy to publish his own data.
There's no "we know the bastard did it, so there" that has to be involved. I load my laptop up with whatever legal programs I like, and I choose to publish the data from those programs any time I feel like it.
