Probably not much to gain in rehashing old wrongs.
I don't think anyone charged with making decisions does so with the express aim of injuring or killing people. Yet that is the end result of stupid or ill-thought policies.
We see it all around us, every day, it's just lucky, I guess, that is most cases the consequences aren't tragic as those discussed above.
Planes, racetracks, mines, aren't in themselves malicious entities. But the decisions made in and around them can have catastrophic results.
If stupidity was a hanging offense, there wouldn't be many of us who would escape, because I doubt if anyone can say, hand on heart, that they haven't done something very stupid indeed.
It's the lack of accountability that gets up my nose, because without that there is little ability to change processes and ensure the bad choices aren't made again.
Butt- covering is an art form.
