Once convicted, it is my opinion that the 5th Amendment does not apply to the convicted person for that crime. It should be mandatory in all possible Capital Cases, that the person be given a lie detector test under sodium pentathal (or better if available) and at least 2X. If they pass, a death sentence would be ruled out and a reinvestigation mandatory. JMO

Interesting idea.
In a general sense, should we consider a change in our judicial system? We have adapted all other systems based on new technology. The judicial system already deals with new forensic evidence, not possible even 5 years ago.
If there was a truth detector, would we want to use it in court? It could put lawyers out of business.
