This reminds me of a news story back in the day. It was a dude on trial for burglary. He said he was innocent of his charges. His proof was a detailed ledger book of all the shit he stole, where from, how much he got, and who he sold it to.

If I remember correctly he was found guilty of the crime he was on trial for. They also used the ledger to convict hom of other crimes and arrested a bunch of other folks.
