Arson Gang Busters was a slick little Republic programmer highlighted by several well-staged miniature sequences, courtesy of the talented Lydecker Brothers. Robert Livingston plays a firefighter who feels that the police aren't moving fast enough in tracking down an arson ring. Livingston decides to do a little sleuthing himself, ultimately going undercover and joining the crooks. It turns out that the culprits are insurance underwriters, seeking a quick turnover by creating their own "accidents". The 65-minute Arson Gang Busters was later reissued to television as the 54-minute Arson Racket Squad. ~ Hal Erickson, All Movie Guide
