accurate?
Under what circumstances will it be used? For those serious
cases such as rape, murder or they will use it on those small cases
too?
There is a lie detector test in Singapore, but it is only used
by the Singapore Police Force. On a side note, results from such
tests cannot be used as evidence in court.
During such tests, the interrogated person will be asked
questions, and if he is lying, his pulse will go abnormally high,
and that will be detected by the machine.
This test is not extremely accurate due to the fact that some
people panic very easily, and others know how to keep their calm
even when they are lying.
This test can be used for any cases by the police, as it is up
to their discretion, though usually they won't use it if they can
come up with ample evidence to deal with the suspect(s).
