A recent report determined that although only 10 percent of those in police custody in the city of egan volunteered to undergo a polygraph test,40 percent of those related from custody without being charged had volunteered for polygrapic test.Clearly,suspects in custody who had volunteered for the polygraph test were much less likely to have committed their crime than those who did not volunteer.

Out of scope.
