(Providence, RI) -- The Rhode Island ACLU is filing a federal lawsuit against the state police for abusing its power. The suit claims state police retaliated against 25-year-old Marissa Lacoste, who did not want to be an informant in a criminal investigation. The ACLU says in the suit that state police used a questionable law to bar Lacoste from her job as a waitress at Twin River Casino when she refused.
