Md. Code, Pub. Safety § 3-504

(a) In this section, “quota” means the mandating of a finite number of arrests made or citations issued that a law enforcement officer must meet in a specified time period. (b) A law enforcement agency may not: (1) establish a formal or informal quota for the law enforcement agency or law enforcement officers of the agency; or (2) use the number of arrests made or citations issued by a law enforcement officer as the sole or primary criterion for promotion, demotion, dismissal, or transfer of the officer. (c) This section does not preclude a law enforcement agency from: (1) using quantitative data for arrests, citations, and other law enforcement activities as management tools or in evaluating performance; (2) collecting, analyzing, and applying information concerning the number of arrests and citations in order to ensure that a particular law enforcement officer or group of law enforcement officers does not violate an applicable legal obligation; or (3) assessing the proportion of the arrests made and citations issued by a law enforcement officer or group of law enforcement officers.
