Tracy Harpster, a deputy police chief from suburban Dayton, Ohio, was hunting for praise. He had a business to promote: a miracle method to determine when 911 callers are actually guilty of the crimes they are reporting. “I know what a guilty father, mother or boyfriend sounds like,” he once said.
Harpster tells police and prosecutors around the country that they can do the same. Such linguistic detection is possible, he claims, if you know how to analyze callers’ speech patterns — their tone of voice, their pauses, their word choice, even their grammar. Stripped of its context, a misplaced word as innocuous as “hi” or “please” or “somebody” can reveal a murderer on the phone.
So far, researchers who have tried to corroborate Harpster’s claims have failed. The experts most familiar with his work warn that it shouldn’t be used to lock people up.
Prosecutors know it’s junk science too. But that hasn’t stopped some from promoting his methods and even deploying 911 call analysis in court to win convictions.

No Stephan, police did “not murder” all the people they did shoot.. They are confronted with a very violent society, many of whom think guns are the way to resolve issues. The vast majority of those killed by LEOs were a direct threat to the officer and/or the public. Then there is a substantial subset that ae committing “suicide by cop.”
That is exactly how many people police killed John, police shot many more.

But I certainly agree we are a very very violent society.
We are becoming a more and more violent society, but the answer is not to allow officers to get away with killing people. No American should be allowed to kill another American, no matter what the scene or the words said on a phone call. I have studied Psychology and I know a person cannot use an unscientific method like the one used can be verifiable scientifically. Science proves this and I dare anyone to say otherwise because they will be WRONG. We need to get rid of the GUNS, even in the hands of police and sherriffs. We should go back to the way the United Kingdom worked with the police only carrying “bully sticks”.
