Just a minor point but he wasn't "caught" with anything.

Riiight... not yet, however IF the information the housekeeper turned-over to the authorities proves to be true then he's got a lot of explaning to do: in front of a judge. Also, if everything he had was on the up-and-up then he'd have receipts to show and a physician or pharmacist attesting to the legal prescriptions and sales.
We'll see what the investigators turn up in the coming times.
