Apparently calls made in the past were made locally so JB naturally thought it would continue that way and they'd know to come out.
IF such was the case, and frankly, nothing said previously leads me to believe it, there's NO excuse for Nevill not calling 999 immediately, and no excuse for JB, had he been party to such knowledge, not conveying it when he made his call, ie, reminding them that previous calls had been made concerning her behaviour.
I'm not blaming you, Lookout. I'm certain it's something you hope to be true. It sounds like something the CT would put out, possibly originating from JB, but it's a bit late in the day for him to start remembering it now.
