Boing Boing is keeping track of what's happening to the guys charged with planting the "hoax devices" of Aqua Teen Hunger Force Moonite LED signs in Boston (which were misidentified as terrorist threats and sparked a costly city-wide alert) a few months ago.
Prosecutors in Boston finally dropped the charges against guerilla marketers Peter Berdovsky and Sean Stevens, who were hired to place the signs all over Boston. They had served a collective 140 hours of community service.
It turns out, there was actually a "hoax device" of fake pipe bombs planted at the same time by two workers at Tufts-New England Medical Center. Those guys, however, got off with just a slap on the wrist. No community service, just suspension without pay.
