Somebody recently sent me a link to an article by Jed Radoff entitled “Why Innocent People Plead Guilty”. Radoff’s article is an indictment of the plea-bargaining system currently in operation in the US. Unsurprisingly given its title, it argues that the current system of plea bargaining encourages innocent people to plead guilty, and that something must be done to prevent this from happening.
I recently published a paper addressing the same problem. The gist of its argument is that I think that it may be possible to use a certain type of brain-based lie detection — the P300 Concealed Information Test (P300 CIT) — to rectify some of the problems inherent in systems of plea bargaining. The word “possible” is important here. I don’t believe that the technology is currently ready to be used in this way – I think further field testing needs to take place – but I don’t think the technology is as far away as some people might believe either.
What I find interesting is that, despite this, there is considerable resistance to the use of the P300 CIT in academic and legal circles. Some of that resistance stems from unwarranted fealty to the status quo, and some stems from legitimate concerns about potential abuses of the technology (miscarriages of justice etc.). I try to overcome some of this resistance by suggesting that the P300 CIT might be better than other proposed methods for resolving existing abuses of power within the system. Hence my focus on plea-bargaining and the innocence problem.
Anyway, in what follows I’ll try to give a basic outline of my argument. As ever, for the detail, you’ll have to read the original paper.Read More »Stopping the innocent from pleading guilty
