Milwaukee police ad keeps you in suspense

This recruitment ad for the Milwaukee police by Cramer-Krasselt really builds the tension. A woman walks down an alley late at night, her footfalls the only sound. Clack-clack-clack. We know something bad's going to happen. We just know someone's going to grab her. There'll be screaming and bloodshed. Clack-clack-clack. Right? The clip's riveting, and succeeds because it subverts our expectations, eschewing a violent and loud ending in favor of a subtle and quiet surprise. We'd all like to live in a world where we'd never have to look over our shoulders to see who might be lurking in the shadows, preparing to do us harm.
