People use the words “chicken shit” all the time. This fella, though, is accused of doing much more than using the words. As seen at todayskccr.com:
Prosecutors say [Tom] Parsons  , following a dispute with the county treasurer over a vehicle registration, placed the registration card in chicken feces and mailed the material to the official in a zip-lock bag. The first-class mail piece was sent from the Pierre Post Office.
Brilliant! They’ll never trace it back to you… The plea?
Parsons entered the plea to a single count of Injurious Articles as Nonmailable Friday afternoon before U.S. Magistrate Judge Mark Moreno in Pierre Federal Court. A trial date has not yet been set.
In the mean time …
Following a discussion on conditions, Moreno released Parsons on a personal recognizance bond with supervision meaning he has to remain in contact with the parole office. Parsons also can have no contact with postal service employees except for regular transactions during the normal business day.
