A federal appeals court has reversed a slew of convictions of extortion and racketeering against two Teamsters who were found guilty in 2014 of using the threat of pickets to pressure businesses into hiring union workers. The reversal of the convictions against the former Teamsters, John Perry and Joseph "JoJo" Burhoe, is another setback for the US Attorney's office, which last month lost a high-profile extortion case against four other Teamsters accused of shaking down producers of the reality television show, "Top Chef."
