He’s still a racist killer who shoots blacks for sport . . . or something.

(Reuters) — George Zimmerman’s defense team is growing, suggesting that he’s planning for a grand jury indictment and a subsequent criminal trial. Interestingly, his new attorney has begun releasing some previously unknown facts.

Did you know that, on the night of Trayvon Martin’s death, Sanford police gave George Zimmerman a voice stress test?

They did, and the results probably contributed to his release [he passed].

A voice stress test is like a polygraph, but instead of measuring heart rate and blood pressure, it looks for changes in an individual’s voice patterns that are thought to suggest psychological stress. With the help of software, investigators record a suspect answering baseline questions and then compare them to answers about the case.

This technology is not unique to Sanford. The National Institute for Truth Verification, a manufacturer of the technology, claims that over 1,800 local, state and federal law enforcement agencies use their product. They also claim to have trained U.S. Military personnel.
