In Nivens's stories, the demand for transplant organs got so big that condemned criminals were broken up for their spare parts. Instead of lethal injection they were anethetized and cut up. Brain discarded, everything else used.
Of course the demand still exceeded the supply, so capital crimes kept dropping to more and more minor crimes -- until even excessive speeding tickets was a trip to the meat locker.
Still, not enough organs were available, so it created a demand for "organleggers", who would grab some schmuck off the street, and break him (or her) down into spare parts.
What you describe is frighteningly similar to what is going on in China. They execute far more people than the rest of the world combined and their preferred method of execution is a bullet in the base of the skull. This is all done so they can harvest organs as efficiently as possible. And things like tax evasion are capital offenses.
