I can’t see any justification for saying “It was 30 years ago, too late”- that just means they managed to avoid a proper enquiry at the time, so if anything makes me think that the whole cesspit should be raked over- who did what, and who (at every level) conspired to hide it.
Mmm. On the one hand, I reckon it’s essential to watch the watchdogs. And I reckon it’s worth keeping the glare on, to remind people today that they can’t expect to get away with similiar. But, on the other hand, there’s more recent police and justice abuses that could do with investigating, probably that would make more sense.
