After giving a warning to someone on the street who was about to light a cigarette, Judge Dredd was called to a bank robbery in progress. Dredd found a discarded cigar butt at the scene, and tracked down the purveyor. When the perps came in to the shop bragging about the robbery, Dredd confronted them. One man gets away, so Dredd chases him on his Lawmaster. The man tried to hide in a building, but it was the Smokatorium, and he couldn't breathe inside without a special helmet. Dredd got him when he came out again.
