There won’t be any riots if Trump is jailed, let’s be real.
Also, Trump plainly has no effective right to Secret Service protection at Rikers. Adams can simply refuse to admit the protective detail - not like Biden will go to court to get an order forcing their admission. Even if Adams lets them in he can’t let them have firearms - no guns in prisoner areas is pretty much corrections security 101, and it’s not like the SS can do much unarmed.
