3:10 to Yuma
After your prisoner Ben Wade kills the first guy in your posse, consider handcuffing him BEHIND his back, especially since it didn't occur to you to search him for weapons. This should help prevent subsequent killings of members of your posse and should cut down his escapes by 50%. Oh and if he's getting in your heads by running his mouth, consider gagging him, like with maybe one of those bandanas cowboys usually have handy. That should keep him quiet.
