The person filming is Israeli. As he watches the cops back up and back up while the knife wielder advances against them, he says in Hebrew: “They don’t know how to confront a person! Drop him!”
I found that comment a complete explanation of current European thinking on how to deal with the Islamist menace. A hundred years ago a British bobby would not have backed up and backed up. They would’ve killed the SOB.
They Taze the guy pretty much intermediately bring him to the ground then kick the crap out of him and disarm him so I am unsure what his criticism is.
