How about the other way around? The wife-—who never wanted guns in the house, etc, etc, etc, now has one because she is terrified of the separated/divorced boyfriend/husband and he has made plenty of threats.
HE can turn HER in, and now, she is completely disarmed, and he can attack here-—possible not for the first time!!
This law will have terrible consequences. Jerry Brown is nuts.
That will happen too, but not as often as the vengeful ex wife looking to hurt her (soon to be?) ex husband. I betcha.
You could reasonably expect that his concerns about her will be disregarded by most judges while her concerns about him will be regarded as being solidly rooted in good judgement.
