Omaha police fire officer who killed unarmed man during no-knock warrant; union appeals.

Omaha Police Department has fired officer Adam Vail, who shot and killed unarmed 37-year-old Cameron Ford during a no-knock warrant last August. The termination follows a department investigation and the police chief's recommendation. Despite calls for Vail's dismissal from Ford's family, the county attorney decided not to bring criminal charges against Vail, stating he acted within the law. The Omaha Police Officers Association has appealed the decision, seeking to reinstate Vail through arbitration. The case has sparked debate over the use of no-knock warrants.
