The Lie Detector  - Investigator's best friend.
The lie detector machine as what i have heard is 90% accurate but can a chronic liar who eats and breathes lies survive and pass the lie detector test or will he fail? Can he manipulate his answers? Which is better, man or machine? In the vain of Kasparov vs Deep Blue the computer.
