So its like in modern day shooters where everyone wears the same brown stuff and you sometimes shoot at your own teammate thinking they are the enemy.
sadly real life doesn't have the red names over enemy heads and friendly fire
clearly this isn't the right approach, but i'm a bit baffled what would be the 'right' approach for the police in this situation where you have a split second decision with bloodied men charging at you.
I guess the life lesson is, if you are ever in a hostage situation and find yourself wearing similar color shirt as the assailant, do what you must to get a shirt thats vastly different color, or just get rid of the shirt with some excuse.
