Is it bad to refuse a polygraph?

How are Lie Detectors used in criminal investigations?
Lie Detectors in Criminal Investigations In any criminal investigation, the state must be able to produce enough evidence to convince either a court or jury that the accused has, beyond a reasonable doubt, committed a crime. In order to prove its case the state—through its police, prosecutors, and investigators—has to gather evidence.

When to hire an attorney for a polygraph test?
If, after consulting with your attorney, you decide that you want to take a polygraph, it’s always better to hire your own test administrator instead.
