Beyond fucked up , guy bleeding from the head and immobile all the cops just walk on ,finaly a soldier reacts.
Seems that the two officers present have been suspended for shoving the old man. But I take slight issue with your description of the events.
1. The cops don't "just walk on". One does stop and is told to move away; the ones who did the shoving appear to stand around the old man while the guy with the rolled-up sleeves gets on his radio. Presumably he's reporting the incident and requesting medical assistance. They move their line ahead of the old man and at least one more moves to stand near him. But you're not gonna stop everyone moving for one person, are you?
2. The soldier/Guardsman in question doesn't "finally react". He, the grenadier, and at least one other police officer move to the old man. None of the officers appear to be medics; they're almost all in riot gear and I don't see anything that would identify them as medical personnel. Footage from another angle suggests that the soldier who knelt down next to the guy took medical equipment from his backpack, so I'm thinking he was the only medically trained person immediately there, precisely because an extra non-police medic is gonna be able to help people when the riot police are busy maintaining their line.
Now, as far as I'm concerned, those two officers did not react appropriately to the situation. They've been suspended, there will be an investigation, and presumably they will get treated accordingly. At first I thought maybe it looked like the old guy was reaching towards the cop's belt/sidearm/taser but looking at the video in slow-motion and fullscreened, he has a phone in his hand. So I don't know what he was saying, I have no idea what he was trying to do, and I also have no idea what mindset the cop was in when he shoved the old guy. But it's my opinion that the officer shouldn't have shoved the old guy, or at least not so hard. That he seemed to be concerned about the man is at least positive?
I do slightly agree with
@308pirate , though. If you're going to go to a protest or whatever and you're going to get up close and personal with a police officer in riot gear, you really have to expect that your day may start going not-so-well
quickly. Doesn't excuse the officers' actions, but doesn't put the old guy 100% not at fault, either. Frankly I hope the old fellow survives his injuries and gets to tell his side of the story, and that more information comes out so that we can all make more informed opinions about what happened there.
