Wasn't blaming the HSE, I worked in mining here in Canada and the safety regs are very strict (much more so than the USA)
But claiming that the accident rate drop is due to them is like me claiming that the rate of deaths due to Viking attacks is down to the local council's new CCTV system. 1st millennium, no CCTV - lots of raids. 2nd millennium, CCTV introduced - fewer raids, 3rd massive surveillance - no vikings.
