If the people holding the Christian signs were assembling peacefully, and they were, then every cop who let the violence from the Muslim criminals continue should lose their jobs. Just imagine if it had been Muslims holding signs having things thrown at them from Christians. That would have made headlines in every liberal rag and the opening story on all the alphabet networks. But since it was Christians being assaulted by Muslims.... crickets from Big Lib Media.
And that is the simplest, clearest reality test.
As you said, if hundreds of kids at a Christian youth camp gathering were throwing items at a small group of Muslims protesting against them, the story would be on every news channel condemning the racist parents of the violent kids.
You know it.
