A prisoner at the local jail, Kent Cool, was awaiting trial on conspiracy to commit tax fraud charges when he learned that one of his codefendants who was also in jail, Miles Friend, was going to become a state's witness and testify against Cool. Cool saw Friend at lunch and told him to "keep his mouth shut." At Cool's pretrial hearing, Cool put two fellow prisoners, Blank and Macaw, on his witness list even though the two men did not testify. Upon return to prison, Blank and Macaw beat up Miles Friend. The government then charged Cool with conspiracy to retaliate against a witness. Does the government have enough evidence to sustain a conspiracy conviction to tamper with a witness against Cool, Blank, and Macaw?
