Responses to Presumed Guilty

Experts in law and psychology watched Presumed Guilty and reacted to Antonio's case. Their essays shed light on what causes wrongful convictions, the Mexican justice system and why reform is needed in Mexico and in the United States.

"The case against “Toño” was built on the basis of a single eyewitness identification.

"There will always be innocents convicted and guilty people acquitted. Criminal justice systems seek to strike the best balance, keeping such error to a minimum.
