Better still, when they indict anyone who had monitored conversations with GP, the government MUST give up those tapes as part of disclosure and as part of providing evidence contrary to their accusation.
From an investigator’s point of view, be careful with wires because sometimes they come back to haunt you with exculpatory information.
Its possible they didnt ask him to wear a wire for that reason..but I bet they did
They at least monitored phone calls
