"Just an aside - when it has been demonstrably shown that the likes of paedophiles and murderers can cartwheel through the BA hoops and slip through the net."
"By contrast Monarch still (as I write) do not simcheck or extend the interview past a casual chat on flying history and their motivation to join the company."
I know that my reply is off topic, but please bear with me.
I am defending BA here.
Monarch had an FO, who was jailed for 6 1/2 years in about 2006 for paedophilia and child attempted rape.
How did that interview go? What was his motivation to join Monarch? To be near his home in Northants in order to carry on his filthy predilection.
And, you wonder, how do I finish this reply? Well, I could tell you that before he fooled Monarch, he was a pilot at easyJet. And before that, a cadet at jmc Airlines, via CTC.
So, you see, not everything is as simple as it seems.
Anyone, and I do mean anyone, can slip through several nets.
