I don't believe a TRO is really proof of any kind of guilt and nobody should be fired because one is filed, but I'm not sure that level of nuance gets through.
EDIT: Reading again, sounds like the guy probably filed some kind of police report against her and got the DA to file proper charges, which is a whole other can of worms, in which case I agree on both counts.
What I'd suggest as a balancing mechanism to avoid the abuses which, yes, do in fact happen by that means, is to make the orders mutual. That is, neither party may come in contact with, approach, or communicate with the other, and both are subject to further legal restrictions for violating those terms.
A slow judicial system drives up the cost of the innocent getting a good legal defense. It also delays consideration of new evidence that can exonerate the innocent that have been convicted.
The 6th Amendment to the US Constitution recognizes the need for judicial speed, even if court cases have effectively gutted that amendment (like the 4th with civil asset forfeiture).
A mere accusation can deny someone their constitutional rights, in additional to other costs such as losing their job.
We can't have a system were a mere unsubstantiated accusation has legal consequences.
Screwing that one up also sends us back to a really ugly place.
Specifically the 2nd amendment… for a time.
I don’t really have a problem with that as far as it’s impermanence goes.
The rest is difficult due to the nature of domestic disputes. I don’t have a good solution there.
