I remember thinking the same when we had the riots after that toe rag got offed by the Met back in 2011/12 whenever it was. I think its a training culture thing....we were encouraged to go in hard & fast to bring in the ring leaders with the snatch squads & disperse the others with a few well focussed baton charges or full chatting the Pigs at them.Regarding public order,I think back to the recent(ish) riots. Admittedly watching from a distance, I thought that plod seemed reluctant to go in hard. I expect that if this is the case,it was for political reasons not because the officers involved didn't want to. To me,it looked like the cops were losing, and a bit of NI style stick and shield would have ended it a lot sooner.
