Document 4: Baltimore Police Department: The Baltimore Police Department (BPD) provides police services to the City of Baltimore, Maryland.

Document 5: 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.
