I would say "no" - but if that actually happens, we are well outside of standard legal procedure, so whether or not might makes right - it does get things done.
So… I'm not sure what that is, to be honest. Why are the police against a wall… And if they have been pushed to a wall, I believe SOP is to go "apeshit" on the crowd to clear a withdraw.
… And if the crowd is trying to go somewhere… Like up that staircase… Why continue badgering the cops who are no longer guarding anything but a damned wall?
Not to say that all things in a protest must make sense - but this looks a little … Odd…
You think you get some kind of special reward for being a cum guzzler or something?
