See my #28, and the link therein. The media hype is "she only fired a warning shot". The reality is her bullet narrowly missed his head, making it more likely she just missed and then claimed "I was only doing a warning shot".
Still, the question remains, is that enough for a 20 year sentence in prison, much less the 60 years that the prosecutor now wants?
I remember reading in the specifics of the case that yes, she did seem to be carrying out an act of domestic violence with threatening. But typically that rates as a serious misdemeanor or low grade felony.
