I was compring it in the way of confronting an individual who had used a vehicle/knife to attack individuals, so yes I think there are many comparable instances.As for "hundreds of cops who have been in much worse situations with much less backup" - we are here talking about a terrorist who had just ran over dozens of people and then murdered a cop, lets not pretend that there have been that many incidents that British cops (or any cops tbh) have had to face "much worse" than this. What happened that day was unprecedented in the UK (at that point) and had only been seen a couple of times in Europe.
With regards to comparable incident, I can think about the '81 riots facing petrol bombs, bricks, vehicles charging at you and scaffold poles made into spears.
I can think of confronting PIRA and UDR gunmen on the main land (that's not talked about much) or walking into pubs where serious criminals are all armed...
... with sawn off shot-guns, revolvers and submachine guns, all while you've got your trusty baton and in the middle of nowhere (near Ainsdale) out or radio range.
Walking into a pub when four men are trying to slash a man with broken bottles and glasses and there was no armour, spray or tasers. But you went in alone!
Like I said, perhaps it is a generational thing but I do feel he should have acted or taken command as, from experience, that was what was expected.
