Firing "at" people could be attempted murder or all the way down to negligent discharge or something, depends on the details of the circumstance (what "at" means) and any plea deals and how vigorous the DA wants to be about it. And this could have all happened before everything wound it way through the courts and he was found guilty of attempted murder even if it was the felony route. It's hard to say just from that much how fucked he really is (well, until the next time he does something like this which sounds fairly likely to happen as his life continues on its present course).
The fact that they're going after him for having the firearm under the protection order instead of for being a felon makes it likely to me that he wasn't a felon at the time he was doing all these shooting-ats.
