Well, at the end of the day, it's her that made a total fool of herself. I think it's time you called the mental health crisis team, this woman sounds like she's dangerous and the cops refuse to do anything. If the 'team' turn up, they HAVE to assess her, they won't just take her word for it at the door and leave. They usually turn up in the rubber truck, so I'd be making a cuppa and getting the binoculars out and wait for the show! It's quite a sight seeing someone being taken away in the rubber truck when they're screaming their innocence.
If you haven't already, I'd be contacting legal aid or one of the other groups that give the first consult free and seeing what they have to say. Those type often advertise on the TV. Legal aid is actually quite expensive, so a private solicitor might be cheaper after the first go. At least you;d know from one consult if there's anything you can do. I'd be making a point of telling them that the cops don't seem interested.
I also think it;s time you contacted the media. The people at A Current Affair are really nice, I've dealt with them before and I know they'd love a story like this. Generally when people like the gumboots are approached by someone like ACA, they go ballistic and make total fools of themselves. ACA would be better than Today Tonight, because most rural areas don't get TT.
Have you done anything about surveillance cameras? That would be my next move, then the cops couldn't come back with the watery excuse that they know they did it but can't prove it. What are you supposed to do, wait until they've hurt one of the kids? It sounds like they're getting desperate enough to do something really stupid, so it's only a matter of time until they start targeting the kids.
I'm still chuckling about the fact she wore eggs in her head when she went down the street. That's a crack up! Sorry, I know you're upset, but what a tosser!!! That alone would be enough for the mental health team to take her away. If they take her away and she leaves, or she just refuses to go with them, she gets arrested. Plain and simple as that.
Get some cameras set up around the place.
