I went to the Post Office to send some pics to a grandparent and I had to register it as Media Mail. Lovely. The Postal Worker informed me that anything that they deem suspicious (too fat of an envelope) they can confiscate and open. It is marked with a special stamp and costs extra. My mother in law recently sent me some JC Penny catalog pages and LO! and behold the damn thing was open. Some threat. Here is the publication. You can request the flyer in the Post Office. It's blue.
