Of course, it would be absurd to polygraph all 25 employee's.  This would be what I call abuse of the polygraph instrument. The polygraph instrument wasn't intended to be, and shouldn't be used as an elimination tool.  I will guarantee you that 22 out of the 25 employee's, if interviewed properly, will be eliminated right off the bat as suspects.  You might find that one of the employee' was probably on vacation when this incident occurred.  If the investigator who is assigned this case does what he or she should do, then at the most, only two or three employees should be polygraphed.  The polygraph instrument is a great and reliable investigative tool, that's right, investigative tool, if used properly.  So stop bashing the polygraph and support it.  All of you who have taken polygraphs and failed, blame yourselves.  Let the truth be known, you got caught lying.  End of story
