I must be missing something. What’s actually the crime or scandal here?

Haigh: “Help, I’ve been mugged”
Police: “What did they take?”
Haigh: “I can’t remember exactly what was in the bag, I guess my money, my bank cards, my keys, my work phone”
Police: “Ok”
Haigh: “Oh, wait a minute, my work phone was at home, they only threatened me, assaulted me and took the other stuff I mentioned”
Police: “Your list was wrong? Ha! Then it is YOU who is the criminal, not them!”
Government, ten years later: “Also, you’re not allowed to fix our railways or have a job”
Tories: “Unlike all our politicians who merely do things like millions of £s of fraud, destroying the economy and endangering the lives of millions of people for their own personal profit - this horrific excuse for a human once put something in a list and then realised it shouldn’t have been on the list, so a decade later, it’s only correct that they shouldn’t be allowed to have a job”

I assume I’ve missed something key here.
