OK, so what have we got her ? Al Sharpton being open and clear about him and other people having a march outside the contenvtion. March and riots are two different things.
Then we have an idiot on twitter stating that if Trump wins he and some other folks are gonna incite riots (and he says "incite", he did not said he will participate ot riots, he did say they will be riots, he just said they would incite riots, they would do their best in order to have riots but there's no roffs it would have worked).
The Black Panthers said there would be ********. They did not said they will be the ones doibg ********. To me that kind of statement is more a warning than a threat.
You said they cancelled all that because the Patriot Riders have made their presence known. If those black folks wre planning massive riots with hundreds or thousands of people rioting, and pillaging the city I don't think they would have cancelled it just because of the Patriot Riders. It's not like the Patriot Riders will bring the 180,000 of them to cleveland, the "rioters" would have clearly outnumbered them...
I much more trust Sharpton's statement about them cancelling the march because of what happened in Dallas and Baton Rouge. Imagine the bad piublicity that would cause a police shooting just a few yards from the convention. If you don't want Trump to be elected, creating the circonstances in which such a shooting may happen would be 100% counter-productive to BLM and other movements fighting police *********
