Death Devices Modern Marvels : Season 7 Episode 37

The hangman, guillotine, gas chamber, firing squad, and electric chair are just a few of the ways in which societies have rid themselves of those who committed capital crimes. And throughout history, a select few have developed the devices that have carried out the mandate of the people. This is the dark story of those inventors and the macabre history of execution mechanics--from the first "stone" of antiquity, the dungeons of the Inquisition, and Nazi death camps to today's sterile injection chambers--with a peek at the future of death technology.
