The whining is the point. And anyways more of this stuff against them means they can whine more and get on Fox News about the "dangerous escalation from far left antifa", they think this will help their side of things and perhaps bring federal help or get liberals to agree that the protestors are all violent terrorists and that they need to give them back their riot weaponry. It's about creating a narrative that it's the forces of good law and order (cops) against the violent forces or destruction and disorder (the protestors who for the most part just want the police to stop brutalizing black people and want some sort of reformation). And that's the point really, obfuscating the actual reason these protestors started in favor of turning it into another culture war item of whether you're for police or protestors. Thus protecting the current status quo by removing the original reason from the conversation.
