Here at this blog, we have a fascination (and ongoing horror) with the number of people who are found guilty by our judicial system and sent to prison — and often, Death Row — though they are almost certainly innocent. DNA testing has freed a lot of them but DNA testing is a fairly recent invention so it's fair to say that this country has probably locked up and even executed an awful lot of innocent people over the years. There are also cases where DNA evidence can't exonerate someone because there simply is no DNA evidence. Dahlia Lithwick has the chilling story of one such unfortunate individual.
