Such interactions aren't uncommon in a city that had 72,159 arrests last year.
But the man in this incident was the grandson of a retired police captain, who asked Horne to intervene to erase the arrest.
A 26-year veteran then overseeing Northwest Detectives, Horne allegedly ordered the officers and their captain to stop the arrest, destroy the paperwork and remove any record of it in police computers. That's a violation of departmental policy, which requires paperwork when officers use force and stun guns, get injured or take suspects to the hospital (to remove the stun-gun darts).
The incident sparked an Internal Affairs investigation that prompted Commissioner Charles Ramsey to suspend Horne for 30 days and transfer him to the Forensic Sciences Bureau. Horne, who had been in line to be promoted to chief inspector (the highest civil-service rank in the department) also was passed over for the promotion. He makes $107,445 a year, according to city payroll records.
"We're looking at it as him being disciplined twice for the same offense," said John McNesby, president of the Fraternal Order of Police Lodge 5, which will represent Horne at the arbitration hearing.
Ramsey has expressed frustration in the past with the arbitration process, which often allows police officers, some accused of serious crimes, to get their jobs back, have suspensions overturned and receive thousands of dollars in back pay and lost overtime.
Yesterday, he said that Horne wasn't passed over for a promotion for disciplinary reasons. Rather, he promoted a better candidate, he said. He currently has no vacancies for chief inspector, he added.
"He certainly has a right to appeal through arbitration; that's guaranteed in the collective bargaining agreement with the FOP," Ramsey said.
