Uckey-duck. Hypothetically, it is possible that the Rs or the Ds could use the No-Fly list to get revenge. But they aren't going to bother with minor irritants, because there are too damn many of them. So one of two scenarios seem plausible to me:
* Crap-Boy really did incite a riot and worse, but his "charges were dropped" story is false or omits key details, such as a partisan DA's office (like Kammy was in SF, more recently) or (more likely, IMO) Crap-Boy got charges dropped in a deal that involved him ratting on his fellow rioters; the plea deal didn't extend to the No-Fly list that was then 10 or 12 years in the future, and what he did really was serious enough to warrant being on the No-Fly list;
* Crap-Boy made up the whole charity-work-in-Greece story and now concocted this pure BS story to explain why he isn't in Greece.
Obviously I lean toward the latter. That set of lies is simpler and more in keeping with DUpipo's Keyboard Warrior character.
