I'm disgusted by this. It's entirely possible she was negligent. So what?
The discharge of a firearm is not a crime worthy of 20 years. Certainly, if one is in fear, yet, keeps a cool head, nobody needs to be shot, and a warning shot is warranted.
Let's look at the facts for what they are. The judge had no choice, as FL law requires a 20 year sentence. That's absurd and clearly unconstitutional. Nobody was hurt. And, the judge, jury and public have no say in the matter.
Can you imagine a situation, slightly different where the same mandatory 20 year law might apply to you? I can. I'm out hunting, and unknowingly trespass on county or state land, (thereby committing a crime) I then decide to fire off a couple of rounds at some coke cans. Do I deserve 20 years, because, that's the rest of my life. It's not likely I'll live any longer than that.
I've hurt nobody.
