Here is what confuses me, she got the PPO but the guy was never arrested. I dont get that at all since he must have done something to be in 'clear and imminent danger'.
An arrest isn't required, nor does any actual violence have to have occurred for her to get a PPO.
All that is required is for her to convey to the judge that she is afraid that he will do something. Restraining orders and PPO's are easy to get. Judges always err on the side of caution with those because if the guy actually does something, they don't want to be the judge that didn't issue the order of protection.
