The Kennel Murder Case (1933)

Wealthy gentleman about town Philo Vance (William Powell) solves yet another case that the stupid cops led by Detective Sergeant Heath (Eugene Pallette) and District Attorney Markham (Robert McEwan) are too stupid to solve.  The Philo Vance series of movies set the pattern for how the police would be protrayed in cenema for the next two decades.  It was not until Dragnet came along that a correction in popular culture was made.
