Mexico's judicial reforms, supported by more than $19 million usd from the U.S., are on trial after a controversial decision in the so-called Rubi case.
The old system, still in effect in many places, was plagued by corruption and confessions extracted by torture.
But anti-crime activists say the new system limits inept judges and overly favors the rights of suspects.
"The system went from one extreme to the other," claims anti-crime celebrity Isabel Miranda Wallace. "What once involved implicating innocent people, now means absolving those who are guilty."
