Next time an armed law enforcement office boards your airplane and wants to retain his weapon, ask these questions. I'll bet the answer to each will be "NO."
1. Do you have frangible bullets in your weapon?
2. Are you protecting a witness on this flight?
3. Are you transporting a prisoner?
4) Are you protecting a political dignitary?
5) Are you a trained Air Marshall and did you advise dispatch that you're on board?
