Kill Most of the Miscreants

If guilt or innocence is assured and doubt no longer exists, why not execute?
New legislation demands death rows be cleared—execute or release. These radical changes in the criminal justice system become possible because of the innovations of one Dr. Max Armstrong. His science allows for the retrieval of memory streams; events are relived and put on public display.
The logs of a detective, Charlie Taylor, provide readers with an unobstructed view of this system's struggles as well as his own fallacies. Crazy Charlie, as some of his colleagues cautiously refer to him, gets an unexpected promotion and begins tracking two different serial killers: the Five Star Couple (who murder in high-class hotels) and Horny Harry (a rapist with an inappropriate name).
When death row is processed, mass executions reveal anomalies in the memory scan interrogation process. Memory banks contain multiple copies of the same event. Are these various memory streams different versions of the same incident? Have innocent men been executed?
Tension mounts when Dr. Armstrong gets charged with statutory rape, a capital crime; it appears he can beat the new science and associated interrogations. Charlie becomes the last resort for solving the riddle of Armstrong and his pending execution.
In the upper echelons of the justice system, a decades-old affair threatens to reignite. In the meantime, one drunken night appears to have destroyed Charlie’s chances with an attractive medical technician.
