I think he’s wrong. The report in the OP of this thread, describes ‘two unarmed officers fleeing the attack’. I’ve not seen any criticism of them anywhere.
Okay - non-civilian, then? - you've commented on whether or not he was 'a civvy', presumably as you feel that makes a difference to how he should have reacted. Thus you agree that his training should have influenced his actions?
I'm asking you whether armed forces training (for example) is...
That's the NATURAL reaction, yes. My point is that I'd expect their training would be absolutely the opposite - to NOT pile in without assessing the situation.
Granted. Having re-read it though, it was 82 seconds between the killer driving his car into the crowd, to the point he himself was shot dead.
Let's guess at 30 seconds for him to have got out of the car and start waving his knives about. Take off another ten seconds from the point Mackey saw...
The other people in the car were not OB.
Given that the entire incident was over in 90 seconds, and there were armed protection officers on the scene, no action he had taken would have made a material difference (except to HIS reputation).
