Are British Police Wonderful?

That South Leeds school I reported on has had another riot.
Most perplexing.
Everybody thought the Police had sorted the security situation out.
And the school is a veritable fortress:
Or not, as the case may be:
This GKN-Chep pallet has been used as a ladder to scale the school fence ever since the first brawl.
It has been left in open sight all that time, and nobody, not even the large groups of Policemen standing next to it, has done anything at all about it.
