I'm so sorry, bluebird. That's really discouraging.
I am embarrassed for the prosecutor. Too many have that mindset--it's one we are working to train out of them. With a case like this, it's better to prosecute and lose than not try to hold the offender accountable.
That doesn't help you, though. All I can say is to keep documenting and reporting violations. Establishing a pattern can help for future cases.
I'm so sorry, though. It's discouraging.
Sending you a big hug.
