When hitting unwanted civilians/criminals, AFAIK we don't lose health anymore when we hit other cops.
That is what I thought.Well I will have to vote No, why? because even if clearly the players from official groups don't loose health, it would be in my opinion a unfair advantage to other cops when they are shooting criminals. Many times when we are having "wars" between criminals and cops, some civilians/unwanted criminals get in the way, making us loose health, with this addition, they would be able to shoot freely without worrying about loosing health.
