When did the woman first discover that her ex-husband was at home? That's actually kind of a moot point, because regardless if she knew he was home or didn't know, if she wanted to go into the home, she probably should have notified law enforcement at the very minimum. This was probably even a requirement of her restraining order against him (I'm just speculating, I have no idea what was in the restraining order). As far as just firing a shot into a wall, I know of no state in the union that includes as part of its use of force continuum, the firing of a "warning shot". The police don't use warning shots and there's a good reason for it, because no matter how well trained you are with a firearm, once you've pointed a gun at anything other than its intended target and pulled the trigger, you don't really know where that bullet is going to end up. It's called the unlawful discharge of a firearm. Florida has had another gun law on the books for quite a while now and I believe it's been fairly successful, it's called 10-20-life. Use a gun in the commission of a crime, 10 years. Pull the trigger on the gun during the commission of a crime, 20 years. Kill or injure someone with a gun during the commission of a crime, life in prison. Her "crime" for lack of a better word, would be violating the terms of her own restraining order, and pulling the trigger on the gun was what got her the 20 years. As far as the white guy goes, there are probably jurisdictions in this country that would've let him off if he had shot his wife too. (Some people just don't take too kindly to adultery!). All that being said, I hope the woman's lawyer is savvy enough to find some grounds for an appeal, barring that, I hope she can be paroled quickly.
