Maybe, in addition to T-Shirts, we should make up anti-slabbing hammers with the logo printed on it. If I were there I would get a sample, open it in front of them, and give them back the plastic. I would liberate as many chips as possible. Its obvious that these people don't care about the chips. I think we should also vow to monitor e-bay for anyone trying to sell a slabbed chip, at least, then we'd know who was involved.
