"Even if they're wrong, you can't shoot back."
Depends on the situation. You'd absolutely be arrested. Get in front of a jury of 12 people and you might have a chance if you have enough evidence for a self-defense claim and the cop acting outside of the law.
If you survive to get in front of a jury. That's a big if. Plus, even if you were falsely arrested and wounded by police and your rights clearly violated... were they violated in that EXACT same way in the past establishing precedent that it isn't ok to stalk/injure people? No? Qualified Immunity. FTP.
Honestly getting arrested would be lucky. If recent years have shown anything, they don't need to be particularly concerned about removing you from the picture more permanently regardless of the circumstances.
I'd highly doubt that. I've actually been on scene of a few LE-involved shootings (ex-paramedic).
If LE "just" shoots at you (i.e. you're not actively firing or an immediate threat - and without commenting on the "should" of that) then... you might be "fine", once you're disabled.
If you're actively firing at LE, they're going to hit you with "overwhelming force" (ever seen a news story where there's 50+ bullet holes in a car, or a suspect shot 15 times, by police? That's "overwhelming force") and any survival on your part is going to be sheer dumb luck and "not very likely".
Only if the jury believes in nullification, which isn't common. The jury is instructed to follow the law. The selection process asks "even if you think they were right, if it's against the law and they were guilty would you issue a guilty verdict?" and people answer "yes" consistently.
