This police training video from the 1980s makes it fairly clear to the green highway patrolman he needs to worry about one thing and one thing only: knives. They're everywhere. And swords. And bums. FACE STAAAAAAAAB! Mildly NSFW.

This video appears to be from Wisconsin or some other Upper Midwestern state and is both cheesy and sincere, offering up a nice mix of knife attacks. My favorite is probably the random Asian-ish dude running down the alley with a sword, but confused bum with a blade is also pretty good.
