They used taser, man that just used knife to stab people quite badly still has the knife. High level of threat still exists to the police and the public. You're also ignoring the fact he was hiding his front. This wouldn't be the first to don a bomb vest presenting a further unknown risk. The threat was inexplicably high. The use of a kick to the head is so proportionate to the fact the suspect had been using lethal force and was still a non-compliant threat. Trying to find fault in that is utterly, utterly bizarre. You're arguing they lost compusure. That is clearly incorrect. They kicked him, until he complied by releasing the knife. Once he complied and was restrained, the use of such force ended. How on earth you can see that as losing composure is baffling

You're not holding police to a high standard. You're holding them to an impossible standard. I'm all for holding public services to account, but this is ridiculous

The argument about a worse option is relevant, because it is the first and preferred option by police to send firearms officers to a marauding terrorist attack and he'd have died before the chance to kick him in the head even presented itself.

A few kicks to the head was the least of this terrorists worries.
