I somehow don’t believe that BO would “call for peace” to quell any riots. Instead, he’d see the divisiveness as a way to build political capital for himself.
BO was quick to rush to judgment. If the riots will break out, he will quickly condemn the acquittal and call for unity.
It’s a nice way of saying “You are right for rioting but you can’t do it forever”.
He will say something like “The court acted stupidly”.
