Actually, I'm involved in some of the fight against abuse agains women.
The lie detector is used as a tool against the criminal, not as a tool to harm the innocent.
At one of the workshops, we learned that in a nearby Texas college town, they are requesting that victims take a lie detector test, because the defense caves when they are informed of a reliable, supportive test.
I was advocating the lie detector test in cases where no bad guy is identified, like if a girl was raped by a stranger. This way a girl couldn't just lie and say she was raped by someone just to get an abortion.
