The case for videotaping interrogations: Of the 220 wrongful convictions in the U.S. that have been overturned based on DNA evidence, nearly 25% involved a false confession or false incriminating statements, according to the Innocence Project. In each of those cases, DNA proved that the confession was false.
Threats and coercion sometimes lead innocent people to confess, but even the calmest, most standardized interrogations can lead to a false confession or admission. Those who are mentally ill or mentally disabled may be particularly vulnerable, but anyone can be dazed when confronted by police officers who claim to hold unshakable evidence of one's guilt. Some confess to crimes because they want to please authority figures or to protect another person. Some actually come to believe they are guilty, or confess to do penance for some unrelated bad behavior. Innocent people come to believe that they will receive a harsher sentence -- even the death penalty -- if they don't confess.
