With less than three months to go in 2012, an astonishing fact has surfaced in the city of Memphis's police force.

Nineteen police officers and civilian employees have been arrested in 2012.

The review of police officers shows that driving under the influence is the leading cause.

In contrast, Nashville police have arrested four of their own officers - two trainees and one civilian employee in 2012.

Three arrests of Memphis officers made by the FBI's Tarnished Badge Task Force involved drugs, illegal use of law enforcement databases, and transporting prostitutes.
