Something I just saw postulated on an LEO site, unfortunately the article was LOCKED as LEO only.
But the question is relevant to civilians and LEOs alike. You for whatever reason have a bona fide "suspect" at gunpoint, yet he is not at that moment presenting a clear and credible threat to you. Most agree that your finger should NOT be on the trigger. But should you also "aim away" or keep your aim on target? What should the LEO do?
