I can just imagine some poor slob, sitting down in a public area near the convention, who pulls a couple of hard boiled ones out of his day pack only to be swarmed by SWAT. Even worse would be the outcome for anyone found to be entering one of the conventions with a couple or few eggs in their bag. I can just imagine him or her being pounced upon, detained, questioned, and embarrassed. I can also see the eggs being seized and examined, x-rayed, sniffed by bomb sniffing dogs, and finally wolfed down by some blob from event security. Perhaps this will transfer to TSA as well and hard boiled eggs will become verboten on airline flights (if not so already).
All the best,
