CourtTV Reports:
An expert in false confessions testified Friday that police interrogations of suspects in the murder were among the most coercive he has ever seen.

What makes this remarkable is that CVSA's were used and:
1. The interrogation and CVSA's were videotaped.
2. The CVSA type "lie detector" used was claimed to be 98% accurate.
3. The suspects were told the CVSA definitively found them liars.
4. The false confession expert is testifying for the
prosecution as it is very clear both were innocent. All charges were dropped and another was charged with the murder. This is his trial. The prosecution must try to prove the confessions are false beyond a reasonable doubt or he walks. Interesting.....
It appears the Escondido PD was using the CVSA just as Jeffrey Nance suggests:
From another CourtTV story:
QuoteJeffrey Nance, a former undercover cop and author of "Conquering Deception," which examines different ways of detecting lies in everyday life, prefers to bypass the question of scientific accuracy and just think of lie detectors as interrogation tools.
"I don't think there's a foolproof way to tell if a person is lying or not," Nance told Courttv.com. "There may be people who don't like me saying that but it's the truth."
