My rural post office was opening my mail. Not all the mail, just mail that was sensitive and private like from a law firm and others.

I complained to usps and they investigated themselves and said no problem here. So there you have it. The post office I complained about investigated itself.

I later on after the investigation get a computer sent to me and the box was opened. I go to the girl at the desk, who opened this. From the back out steps the post master and she says I did.

I knew than who was tampering with my mail. Why was my mail being opened and looked at by the postmaster.
