A judge has to sign off on a protective order first, I guess that is where the due process comes into play.
Usually you have to have some kind of proof to have a restraining order put on someone, you just can’t walk in and demand they have their rights taken away. (usually..)
Perhaps if some violent guy with a nice collection has them taken away from him it’s just another reason for him to go off on the person, maybe it will be the straw that broke the camels back and he uses a butchers knife instead.
Bet if someone tells the cops that was the reason he did it it won’t make the news either.
Sorry, but "usually" you don't need anything but the words coming out of an Ex's mouth. This is bad law in every way. If someone is afraid of someone else's guns, they'd be better off arming themselves, not depending on jackbooted thugs to disarm someone else.
In general that's probably true, but in some jurisdictions they're just issuing them by default in every divorce proceeding, I hear. Often against just the husband in today's anti-male courts, but sometimes against both parties.
