Most federal prosecutions rely on conspiracy statutes to gain advantages that do not exist in other types of criminal cases. One such advantage is the vagueness of the crime itself. Another advantage to the government is the “conspirator hearsay exception” which allows a government witness to repeat one conspirator´s out of court statement to establish the guilt of another defendant. Yet another advantage is the prosecutor´s ability to try all members of the conspiracy jointly, thus increasing the possibility of guilt by association.
