The only thing that *really* bothers me about this story is that the only charges that will stick are disorderly conduct and the catch-all, "computer crime". The problem is that "computer crime" can mean anything from throwing a computer through a window to hacking into the IRS and stealing enough to buy a B-2 bomber, or shutting down a nuke plant using telnet, duct tape, and a wi-fi cantenna.
So in the end this guy may end up a felon, complete with all the consequences (such as gun restrictions), because he was stupid enough to push some electrons into the form of a prank that was in extremely bad taste.
I'm not sure stupidity that doesn't actually result in harm to ANYONE deserves a felony conviction, but that's what they're gonna try to use that "computer crime" charge for.
