But these people do!
Inside the Postal Service, if you have the money and the political connections you can have a piece of mail intercepted, stopped, delayed, sent to the wrong distribution center and more and all it takes is a ‘deal’. Once that ‘deal’ is made cutting if off tends to identify the politician who pulled it off so once a deal, always a deal, until caught. And even then, you can be caught again and again and again for the same theft practices and keep on doing them. (Hempfling v Volkmer 9th Cir) Why? This corruption has been known to the Postal Service for well over a decade.
Mail intended for delivery through the ‘trusted’ Postal Service (involving the 4th Circuit Court of Appeals in South Carolina) was stolen and wound up being found mashed into the glove box of a delivery vehicle before it’s delivery was finished by the Postal Inspectors. They knew about that crime for over a decade but never indicted anyone for it. Seems to have only become a stronger and more organized criminal enterprise.
