I must be missing something basic that all vendors must do. Wouldn't it be simple for the fbi/postmaster to order some drugs themselves and flag the return address? Even if the vendor used a fake address, they could mark where all the packages using the fake address were shipped from and set up a sting.
I just got a package today with the best stealth/decoy I've ever seen. However, it looked like someone tried to life the envelope as far as they could without ripping it. Picture is here. Does this mean they already are watching the vendor?
Feds can do only a few things:
They can order to get general loc, check for prints, and get a profile of package.
They can use profile of package to disrupt business and collect customer info.
They can have postman to lookout for profile and note what blueboxes they were dropped at.
Really thats it. Keep your prints off of it, drop at different boxes around town, and when it comes to profiling, use e-labels, the stamps/tracking sticker combo is pretty dated any no one uses this anymore except drug dealers and old people.
