A soldier was staying at a hotel in Colorado Springs, Colo. when a man came up to his door and asked to check the plumbing. The soldier let the man into his room, but once inside, the man drew a knife and attempted to rob him. The soldier responded by retrieving a gun and forcing the criminal to the ground.
