The law enforcement would support the courts who would side with and in fact are part of the liberal/leftist/apologetic/hate-America first crowd. So yes, I think our police would side with the Muslim lovers whether they want to or not, because if not, the courts would haul them up for hate crimes or for using anything that the lunatic courts would view as excessive force. Our law enforcement can't even enforce illegal immigration laws already on the books because of liberal, sympathetic judges who will support the illegals and prosecute law enforcement for trying to enforce the laws? Why would you think that they would they would be any more poised to put down Muslim rioters or violence with any degree of firmess, when they would be prosecuted for enforcing the laws?
The MSM would try to spin it against the police, but violence done by anyone would be stopped. I completely disagree with your premise, so it's probably best for me not to discuss this further. Thanks.
