On TV, successful female cops populate some of our favorite shows. From Law and Order: Special Victims Unit's Olivia Benson(Mariska Hargitay) to The Wire's Kima Greggs (Sonja Sohn) toThe Closer's Brenda Johnson (Kyra Sedgwick) to Castle's Kate Beckett (Stana Katic), we see women in law enforcement apprehending sex offenders, performing stellar detective work, nailing interrogations, and closing cases. But in real life, women make up a surprisingly small percentage of police forces. 

The U.S. Department of Justice cited the following statistics in the 2010 report Women in Law Enforcement:

In 2007, women accounted for about 15% of the total sworn law enforcement officers in large local police departments. In large sheriffs’ offices, female officers comprised about 13% of the total sworn officers. In contrast, local police departments with between 1 and 10 full-time sworn officers employed fewer than 2,000 female law enforcement officers nationwide (6%). Small sheriffs’ offices across the county employed just over 200 total sworn officers who were women (4%) in 2007.
