Please help forensic science!! A polygraph test is conducted, and the findings indicate that there is an 80 percent chance of deception. What does this mean for the investigation?

The suspect is guilty and should be arrested for the crime.
The suspect is probably just nervous since 80 percent is a pretty high number and usually indicates a false positive.
