If it’s found that he is not a citizen and lied about it, I actually don’t think there will be generalized riots, because I think a lot of blacks will be angry at The One and the party who duped them into voting for him. American blacks do not like foreigners who happen to be black cashing in on their struggles, and I think that’s going to be a significant point.
Places that have a heavy Black Muslim or Muslim population, I suspect, will be the most likely to riot, because those people don’t give a darn about the Constitution or our laws anyway, feed on hatred and will no doubt have been expecting to have the Fruit of Islam (the NOI bodyguards) replace the Secret Service at the WH - and they’ll be disappointed.
They won't be angry at "The One." They'll be angry at "The Man."
