Distracted? Yes, apparently so. Distracted with flirtatious texts.
I really want to here a serious defense of this as being a legitimate excuse for the "mistaken fact" of going to the wrong apartment.
"I was too busy trying to arrange a booty call to realize where I was. So I shot the guy."
This takes out the whole "anyone could make that mistake" defense. If you are too busy texting to notice where you are, that's not a "whoopsie" mistake, that is totally negligent. She wasn't paying attention to where she was. She wasn't overly tired, she just wasn't paying attention.
Use that as an excuse with the judge. Sorry, judge, I didn't know the speed limit. I wasn't paying attention....
