It appears that she will very likely be convicted of misdemeanor domestic violence. If so, she will be prohibited from possessing a firearm or ammunition for the rest of her life regardless of any self-improvement. That, under threat of a minimum federal prison sentence of several years (forgot how many, offhand).
So if she’s attacked by a truly dangerous beast—human or otherwise—she will be at his mercy with no realistic means of defending herself.
There should be a legal remedy, but there isn’t, because...feminists, bar associations, corporate managers, medical lobbies and others who passed the Violence Against Women Act.
I presume that the Violence Against Men Act will be passed soon.
