Ah yes, but then, with such methods a number of failures are to be
expected and the scammers don't care as long as a certain percentage is
fooled. When using this trick to fool someone into telling confidentuial
things it is very uncertain. For once, I've never heard of the police
trying something like this to obtain confessions or information: the
chance of failure in an indivicual case are too big.
