Nope. That's assault. If you're trying to hit me, then you're obviously attempting to hurt me. If you're not trying to hurt me, then I can't guarantee that I won't retaliate and kill you in self-defense if I think you are shooting at me. You probablly would get convicted of assault if you were shooting in such a way that I thought you were shooting at me in plain sight.
If you don't get convicted and it happens a second time, then I can almost guarantee you will get convicted that time.
Then you should be OK with folks privately disposing of known habitual drunk drivers.
