Reckless endangerment. Discharging a firearm towards a human. Assault with a deadly weapon [with an aim towards plea bargaining down to a misdemeanor]. There’s all kinds of things that the DA could do. It was a bad shoot. But it is not a prosecutable one.
In Texas law, provided nobody else got hit and it’s a legal shoot, none of those will stick and it will make the DA look foolish. The DA might lose their election next year because it makes him look like a sore loser.
It also would set a bad precedent for other legitimate defensive shooting and give Soros DAs bad ideas.
Not if he wants to get re-elected in my county. For a short period of time, we had a somewhat liberal DA in my county that liked to try and twist Texas law against gun owners and property owners. The local judge and juries saw through his charades and he was never successful. He was soundly defeated on the next election cycle.
