It seems that you can:
SINCE 1992 the Innocence Project, an American legal charity, has used DNA evidence to help exonerate 271 people who were wrongly convicted of crimes, sometimes after they had served dozens of years in prison. But a mystery has emerged from the case reports. Despite being innocent, around a quarter of these people had confessed or pleaded guilty to the offences of which they were accused.
It seems hard to imagine that anyone of sound mind would take the blame for something he did not do. But several researchers have found it surprisingly easy to make people fess up to invented misdemeanours. Admittedly these confessions are taking place in a laboratory rather than an interrogation room, so the stakes might not appear that high to the confessor. On the other hand, the pressures that can be brought to bear in a police station are much stronger than those in a lab. The upshot is that it seems worryingly simple to extract a false confession from someone—which he might find hard subsequently to retract.
Something to ponder as 2301s dig into prodecural civil liberties.
