If Just One Policeman Has A Different Paymaster ?

Operation Pallial.
Operation Yewtree.
Operation Fairbank.
Operation etc etc.

All current police operations set up to investigate cases of historic child abuse.
All using good, honest policemen who hate abusers and want the truth to out.
All collating and gathering information from the UK police forces.

What if..?

One of the team had a different paymaster ?
All that information...
