He wasn't just shooting at the unconscious guy, but more likely at the whole crowd.
I just wonder why you are responding to emergency call(s) all alone. And then when you arrive to the scene, you start to talk foreign language with them in RP situation which is against the rules. When the random guy arrives and starts to shoot at the crowd, the other 2 guys pull out their guns and starts to shoot at the guy. You didn't search them to see if the guns were illegal or not, neither did you check for their licenses. You can't just ignore it because they're your friend (I suppose as you were talking in foreign language with them). This proves that you are a corrupted agent and probably without bio. However, I'm not the one deciding nor giving out penalties.
