Several of them.  In all cases I'm aware of, it was alleged the
individuals were using OpenPGP to conceal their activity in a crime. 
Covering up a criminal offense is, itself, almost always a criminal
offense.  If the government alleges, "this person used OpenPGP to cover up
the crime and make life difficult on the FBI," the government must do two
things: (a) enter into evidence the fact the accused has access to OpenPGP,
and (b) convince the jury the accused used OpenPGP in an attempt to foil a
police investigation.
