If this is the case that I remember, what happened was that there was some Muslim in the square knifing anyone he could find, so the German dude tackles him and holds him down until the cops show up.
Then the cop shows up, and instead of arresting the Muslim, he starts to arrest the German dude and lets the Muslim loose. Too bad for the idiot cop’s family - the Muslim, once loose, got behind the cop and knifed the cop, killing him.

The communist anarchist cop got what was coming to him for being a traitor and an oppressive government goon. I call it a happy ending.
The thread contained the video showing just what you described of the cop kill’n.
If someone is able to find the full video and post it.
