Shakedown (also known in international markets as Blue Jean Cop) is a 1988 American action thriller crime drama film written and directed by James Glickenhaus, starring Peter Weller and Sam Elliott.
Roland Dalton is a burned-out, mild-mannered Manhattan public defender, and his last case before leaving legal aid is crack dealer Michael Jones, accused of shooting to death police officer Patrick O'Leary in Central Park.
Roland and Marks eventually learn that O'Leary was working with a large number of dirty cops, and purchased designer blue jeans and an expensive car.
Roland at one point breaks into the police station's evidence locker to locate the cassette tape that Jones had in a boom box radio at the time of his shooting.
[1] Roger Ebert at the Chicago Sun-Times commended Glickenhaus for showing a "tremendous amount of craftsmanship and skill" when sacrificing story to direct his action scenes and gave praise to both Weller and Elliott for being "strong, unsubtle but convincing" in their respective roles, saying "It's an assembly of sensational moments, strung together by a plot that provides the excuses for amazing stunts, and not much else.
