Yes indeed. Brian and his panters-on should be kindly shooed away by NZ Police. They really are being unreasonable, and any sensible person would be getting fed up. A bit of goofy fun should not be cancelled because of a violent American evangelist inspired nut cake fringe mob. I am so sick of him.
It's not OK. But the venues have a very legal responsibility under health & safety legislation, and a credible threat is a credible threat.
It is the Police that should be knocking on Tamaki's door. If he and his people spend enough time answering pointed questions about their credible threats...
