If he's a clown plant, they did a good job disguising him as just a nerdy type. But, since at this point, anyone with fatal TDS is likely to act out violently, keep a very close eye on that guy!
Relax. USSS, US Mil, and who know what other assets are there watching and ready to pounce. If we can figure this shit out so can all those people. In any case, message sent, assets on alert, and almost zero chance some TDS infected loon can do anything other than chant until they're removed.
