More a politician than a policeman, he has ties with various Democratic organizations close to City Hall, most notably the politically influential developer Andrew Krawczyk.

Valchek first appears in a meeting with Deputy Commissioner Burrell and Lieutenant Cedric Daniels, trying to smooth over Prez's drunken maiming of a fourteen-year-old.

Valchek pushes for an investigation into corruption at the docks, due to his petty feud with stevedore union treasurer Frank Sobotka.

Observing the lack of diligence from the task force, Valchek coerces Burrell into providing him with a genuine police detail led by Daniels.

Reluctantly, Valchek assigns Prez to a two-month stint on the midnight shift at the district's narcotics unit and accepts a written apology to avoid pressing charges.

When the investigation ends, Valchek delights in personally arresting Sobotka and holds him in the union offices until he can be publicly dragged out in front of the press.

Valchek is surprised and amused when Major Howard "Bunny" Colvin confronts Rawls and questions how to juke the stats with regard to dead bodies.

[3] After Thomas "Herc" Hauk, a member of Royce's security detail, catches the mayor receiving fellatio from a secretary, Valchek mentors him in exploiting the situation.

Carcetti and assistant Norman Wilson both agree that Valchek cannot deal with pressure from the City Council and the minister's alliance, even on an acting basis, but keep the statistics nonetheless.

Facing budget constraints and unable to take disciplinary action for an increase in crime rates, Carcetti opts to give Burrell a pass as long as honest statistics are provided.

To mitigate potential backlash from black voters, Carcetti strategically leaks a story to the Sun with Daniels' photograph, suggesting a consideration for a change in commissioner.
