This isn't complicated.

The hateful and unjust lie of the polygraph test is useful. It allows you to persecute on false pretenses.

They do not want a lie detector. They want a magic button to push to allow them to detain anytime they want. Fail a polygraph? Go to jail. Pass a polygraph? You used terrorist methods to do so.

Friendly reminder that American soldiers in Abu Grahib used rape as a weapon of tourtue.

But don't worry Google isn't developing ai weapons that would be trouble.

You have to define "they". One of the most useful aspects of polygraphs is their ability to spur spontaneous confessions. Most people who leak/serve as foreign agents are not Snowdens, they're largely weak people who's weakness is being exploited by a geopolitical adversary. Put a weak, vulnerable person under the microscope, present even a hint of extra scrutiny and all the consequences that might entail, and they often crack out of semi-irrational fear. I say semi-irrational because while ploygraphs don't often hold up in court, they can be useful in targeting potential suspects for further investigation/monitoring.

It's not all jail cells and Guantanamo bay.
