I have just read that Commons link.
I did not know the officers can appeal a vetting decision. That is an absolute piss take compared to the standards that apply elsewhere in the public sector. No appeals given there.
Also, enough with "words of advice", ignoring dodgy family connections or not obtaining a full employment history.
That isn't any kind of vetting. There are people all across the public sector who have do reach a higher standard. In fact it's hard for me to think of anyone given the power and responsibility.
No wonder we have so many bad police.
