Homicide Bureau (1939)

After being criticized by the Citizens' League for his inability to cope with a crime wave, Police Captain Haines orders his men in the Homicide Bureau to clean up all their cases, but without violating the constitutional rights of any suspect. Detective Jim Logan is ordered to meet the incoming new-head of the Police Department lab and internal affairs, J.G. Bliss, and takes an instant dislike to her over her attitude toward criminal's rights. A murder case is turned over to Jim. Chuck Brown, the killer, informs his gang boss, Briggs, that their blackmailer has been killed and Briggs continues with his preparations to ship a cargo of scrap metal metal to foreign war lords to be used for munitions manufacture. Jim arrests Chuck, but if forced by Miss Bliss to release him on grounds of insufficient evidence. In an attempt to force a confession from Chuck, Jim goes to his apartment and, in a scuffle, causes him to fall through a window. The aroused Citizens' League, through its spokesman Henley, press charges against Jim and he is demoted. He continues to investigate and learns of Chuck's connection with a junk dealer's racket. Jamison, a honest junk dealer, is murdered for refusing to ship scrap metal abroad for war purposes and an eye-witness is killed in a supposed hit-and-run accident.
