Brandon Piekarsky and Derrick Donchak were acquitted of various state charges resulting from the beating and murder of Luis Ramirez. CNN legal analyst Jeffery Toobin is calling for a federal hate crimes investigation. "The facts and circumstances of this case certainly call for at least a federal investigation because it is possible when a group of individuals are acquitted on state charges, that federal bias charges can be brought," explained Toobin.
