Kevin P. Clark: Kevin Clark is a former commissioner of the Baltimore Police Department, who held the position from early 2003 until November 2004.  A former NYPD officer, Clark's term as police commissioner was strained with both the mayor and police department as Clark was involved in domestic issues and an unpopular turnover of veteran officers such as former Major Gary D'Addario.  He was fired by then-mayor Martin O'Malley, resulting in a lawsuit in which he sought $120 million in damages and fought to get back his job.  O'Malley's justification for the firing had been that these accusations were distracting to his duties as a commissioner.

Baltimore Police Department: The Baltimore Police Department (BPD) provides police services to the City of Baltimore, Maryland.  It was originally organized in 1784, after the United States gained independence, as a "nightwatch" and a force of day "Constables".  It was officially established by the Maryland Legislature on March 16, 1853, and reorganized in 1857 by Mayor Thomas Swann of Baltimore.  It is the eighth-largest police force in the US and is organized into ten districts: nine based on geographical areas and the Public Housing Section.  It polices 80.9 sqmi of land and 11.1 sqmi of waterways.

Prior to assuming that post in January 2008, he had served as Chief of the Metropolitan Police Department of the District of Columbia (MPDC) from 1998 to early 2007.

Charlotte-Mecklenburg Police Department: The Charlotte-Mecklenburg Police Department is the police department of the City of Charlotte & Mecklenburg County, North Carolina, US.  With 1,849 officers and 473 civilian staff as of 2014, covering an area of 438 sqmi with a population of nearly 900,000, it is the largest police department between Washington D.C. and Atlanta, Georgia.  The CMPD is unique in that it was formed in 1993 with the merger of the former Charlotte City Police Department and the Mecklenburg County Rural Police Department.  Mecklenburg and neighboring Gaston County were the two counties out of the state's 100 counties to have county police in addition to the sheriff's offices.  County police perform law enforcement tasks in the county with police powers anywhere in the county just like the sheriff, but the sheriff primarily handled the courts and jails.  The North Carolina General Assembly approved legislation combining the two agencies.  They are by statute "county police" in that they have jurisdiction anywhere in Mecklenburg County.  However currently, the CMPD does not have any response areas outside Charlotte but within Mecklenburg County.  The unique status of this situation makes the CMPD "metro" police, and the City of Charlotte has no municipal police department.

The Charleston Police Department has an organization of several different divisions, including a Patrol Division, Traffic Division, SWAT, Bicycle Unit, K-9 Unit, Community Policing & School Services Division, SEU or Special Enforcement Unit, and CID or Criminal Investigation Division.  The current Chief of Police is Brent Webster.
