"The Jigsaw Man" is a science fiction short story by American writer Larry Niven, set in the Known Space universe.
The story was first published in Harlan Ellison's anthology Dangerous Visions, and is included in Niven's collections All the Myriad Ways and Tales of Known Space.
In the future, criminals convicted of capital offenses are forced to donate all of their organs to medicine, so that their body parts can be used to save lives and thus repay society for their crimes.
The protagonist of the story, certain that he will be convicted of a capital crime, but feeling that the punishment is unfair, escapes from prison and decides to do something really worth dying for.
He vandalizes the organ harvesting facility, destroying a large amount of equipment and harvested organs, but when he is recaptured and brought to trial, this crime does not even appear on the charge sheet, as the prosecution is already confident of securing a conviction on his original offense: repeated traffic violations.
