Ex-trooper with KKK ties may lose Nebraska law enforcement certificate. journalstar.com. The Nebraska Police Standards Advisory Council is recommending that law enforcement certification be revoked for Robert Henderson, who was fired by the state patrol for his ties to the Ku Klux Klan. Henderson asked the council on Wednesday to let him keep his certification so he can work as a law officer elsewhere in Nebraska. But the council voted to revoke his certification, citing his neglect of duty and his emotional incapacity. The decision goes to the Nebraska Crime Commission for approval. Henderson was dismissed in 2006 after it was discovered he had joined a racist group. He told an investigator he joined the Knights Party in June 2004. Henderson appealed his dismissal to the Nebraska Supreme Court, State v. Henderson, 277 Neb. 240 (2009) which upheld the firing. I didn't know that practicing your first amendment rights off duty adversely affected your attention to duties and emotional capacity.
