One problem is that TROs are generally not really worth the paper they're written on...Yeah, I'm with you. I don't want abused spouses getting harmed either.
I'm not an attorney, but isn't it easier to get a restraining order than a conviction for domestic violence?
If a legitimately abused spouse pursues criminal charges, but the system fails her, I would imagine a restraining order would be the next thing I'd try.
