You're misrepresenting what was said. All they said was that some people had been up to some very stupid thing, not that the police had a legally watertight case under the TSA. The TSA has never been used in NZ, and is not well-designed for use against any domestic organisation as it is primarily aimed at UN-designated international terror groups. Frankly, any prosecution was always going to be fraught.

The fact that terror charges are not being brought does not affect the possibility that the alleged events happened.

Or is Clint Rickards innocent around here now?
