Valchek, played by actor Al Brown (www.AlBrownIsValchek.com), is the Polish-American commander of the Southeastern district, home to many of the remaining white ethnic neighborhoods in Baltimore. A politician more than a policeman, he is well-connected and is on good terms with various Democratic organizations close to City Hall, most notably the politically influential developer Andrew Krawczyk. In Season 4 Tommy Carcetti suggests that Valchek was named commander of the Southeastern Police District because it is a position reserved for either Greek American or Polish American commanders in the department. His political savvy led to a quick and easy rise through the ranks, despite being disliked by commanding officers such as Commissioner Ervin Burrell and Deputy Commissioner William Rawls. Valchek is Roland Pryzbylewski's father-in-law.
