'Tween a rock and a hard place I'm stuck
Know the knock will be "cop run amok"
His last breath's not my fault,
But says "death by assault",
So this sock-'em-first slob's out of luck.
In Where the Sidewalk Ends (Otto Preminger, 1950), when tough cop Dana Andrews kills Mark Stevens, he assumes that no one will believe it was by accident. Title by punch drunk David Cairns, of Shadowplay.
