BG Orders All CCWs to Toss Their Weapons
On your way home from work, you stop to run into the bank (or a store, or a restaurant, etc). You're finishing up your transaction when you hear a voice scream "Nobody move. Just keep cool and everyone gets out alive." You realize an young man with a Glock 19 is robbing the place. He gets everyone to one side of the building and says "Don't think about being a hero today. If you're carrying, raise your hand. One at a time, you're gonna slowly pull out your piece, put it on the floor and kick it over here. If I find anyone carrying a gun, you get to watch the person next to you die before it's your turn."
You're carrying and you have no idea who else may be. You might be the only one or there might be many more. What do you do? What variable change the answer - If he has a shotgun instead of the pistol? If there are two robbers?
