How many innocents does he kill

Couple things.

A. Im pretty sure he was only wounding the cops and law enforcement types that weren't directly connected to the scams.
B. When the President of the US is a major player in scamming americans out of billions a year and ruining an untold number of lives, then wielding the power of the US govt to hide those actions, anything you do law enforcement suddenly becomes much more morally justified. (and before some asshole pops in here claiming that the US is already doing that in reality, keep in mind it wasn't some vague conspiracy theory within the context of this movie. It's explicitly shown that those in power were incredibly corrupt.)

You're basically complaining that when Luke blew up the death Star, he killed lots of innocent empire soldiers who were only there to serve the galaxy and be good citizens!

It wasn't just law enforcement, like immediately after he asked that guy for his car keys at the gas station and he drives off, it blows up lol. There were people there filling up on gas.
