When you apply for a law enforcement or government position they almost never tell you why you were rejected. At least 50 percent of applicants who make it to the polygraph and personal interview stages are disqualified. If they disqualified someone because they seemed immature regarding use of force, they would never say that was why. People feel embarassed because they told all their friends and family that they were going to be a cop, so they come up with a justification for why it wasn't their fault they were rejected. I could be totally wrong but that's my experience.
