The English government (well, they're the British government, but they don't get to set building rules for the bits of Britain that aren't England) didn't think fire sprinklers were necessary in big tower blocks and schools. Too many regulations you know, it hurts the economy.

Then not just one but two huge tower blocks in London burned down. So how about that, suddenly maybe tower blocks _did_ need sprinklers after all. Shame about all the dead people.
