A constable shall obey and execute all process directed to him from any judge of the District Court of Maryland concerning any matter within the court’s jurisdiction and shall return the process according to its command. He shall serve and levy all executions issued by a judge of the District Court, and in so doing has the same powers, responsibilities and liabilities as a sheriff or deputy sheriff acting in the same capacity if the constable has satisfactorily completed a training program from a police training school approved by the Maryland Police Training and Standards Commission.
