@Humpleupagus That kind of works but these people are in a group. And that logic has been used before especially war prisoners and a large majority of those people will gamble the fact that they don't have enough firepower to kill everyone on the group if everyone decided to run at once.
Because even if you decide to get 5 to 10 buddies to run at once you could reasonably gamble that at least one to two of you will escape even if it's a modern firearm.
And considering it's only one person unless I'm holding a minigun they will probably gamble that I don't have enough bullets in the magazine to kill all of them.
