So can anybody with two minutes and a clothes iron. Actual police announce themselves, state their intentions, follow deliberate procedures, create public reports, answer to bystanders, and generally work to uphold law and order with everybody else. Regardless of how they got the costumes, the aggressors in that video are violent criminals.
They don't just have police badges, they also have patches on their shoulders which is for DHS. This was reported couple days ago that DHS will be coming in to stop the rioting:
Two patches?! Okay then, three minutes since the iron is already warm. The substantive argument is about the complete lack of process and accountability.
Since you seem to be here to reflexively argue, the only thing I have left to say is that you need to realize that the federal government deploying soldiers into American cities against the express wishes of the local governments is utterly anti-Freedom, anti-American, and straight up totalitarian. We're witnessing the destruction of our country, and you're cheerleading to the tune of Party propaganda. It's never too late to snap out of that filter bubble and come to your senses.
You are just being thick on purpose. DHS was deployed because the federal buildings have been getting destroyed. If the local government doesn't want to do it, then the feds have to protect their property. You need to stop believing the media propaganda and think what you would do if your building is getting destroyed.
