Civil libertarians are calling on the U.S. Justice Department to expand a probe into the Saginaw Police Department.

The Justice Department has been examining the case of Milton Hall. He's a mentally ill homeless man who was gunned down by six Saginaw police officers as he threatened them with a knife.

The case has raised questions about how the department deals with African-Americans.

Mark Fancher is with the American Civil Liberties Union. He says his office has received several allegations that Saginaw police officers operate in a racially biased manner.
