My goodness, they ARE complete nutters!! What a shame you didn't have a video set up, that would've been priceless to get that on film. Clearly they're getting desperate now, it's only a matter of time until they come unstuck totally. They are fools, obviously they forgot to pay the cops off, like they seemed to do with the mayor. Maybe they need reminding of other people that could become involved so they can get to them and pay them off first.
Are they still hanging around the school? If so, I'd be photographing that and taking it straight to the police. Or better still, don't approach the school if they're there, just stay around the corner and call the police and tell them there's some perverts outside the school, AGAIN, and could they come and rectify the problem. The law frowns on people sitting outside schools when the people in question don't have kids attending there. It's not just dirty old men that are perverts, it's just as easy for her to get hung for it too.
I still think you should call ACA. Even for no other reason than watching them make total fools of themselves on national TV. I can contact them for you if you like, I've done it a few times before. As most know, ACA isn't really about legit current affairs these days, it's more about neighbourhood disputes and where you can get the cheapest shopping bargains. Your story would be right up their alley. Plus you get a bucketload of free advertising.
I'm still amazed that all this is still going on simply because you asked them (nicely) to stop interfering with your guests! If they want to be seen to be doing 'something', why don't they help out at the local charity store. Bit more glory in that than interfering with your paying guests. The same paying guests that stay there because they want some peace and quiet.

PS: I'm having a shocking time with my email lately, so if anyone has sent me an email and I've not replied, it's because either 1. I haven't actually received the email yet or 2. I've got it but can't reply to it. Every now and then it kicks back in and might send one or 2 messages in the outbox, but most of the time it just hangs.
