Dr Wolfe, a security expert who worked for the US Government before emigrating 35 years ago, said: "Why do we want to allow spying on our citizens? There are people everywhere who are sympathisers of something or other that is unpopular. The whole idea of the law is innocent until proven guilty. Surveilling the innocent - is that what we do to protect anyone or is that what we do in totalitarian society?"
The police have to apply to a court and present prime facie evidence of wrongdoing to get a warrant from a judge. "That's the oversight to ensure innocent people are not getting abused," Dr Wolfe said.
The Prime Minister's office referred the Herald to a briefing paper that said the basic premise that the GCSB not spy on New Zealanders would only apply to its "foreign intelligence activities". This would still mean that the surveillance of Kim Dotcom would still be illegal but it would be able to spy on Kiwis in its other roles of "information assurance and cooperation and assistance [to the SIS, Defence and police]".
Safeguards would be met by beefing up the oversight role of the Inspector-General of Intelligence and Security, who would be able to initiate its own inquiries. The inspector would report findings to the Prime Minister who could keep it secret.
Dr Wolfe said he was concerned to see the erosion of privacy throughout the world which was driven by technology and excused by fear. "The whole idea of article 12 of the universal declaration of human rights [freedom of interference of privacy, family, home, correspondence] is being destroyed.
"We have to protect everybody [was the rationale]. We are going to make you more secure by taking away your freedoms? I don't feel more secure when I am not free. I feel less secure when I'm not free."
The weapons of mass destruction comment was "pap".
Dr Wolfe said he thought the illegal surveillance of Kim Dotcom was a "travesty".
The vast majority of cyber attacks were commercially motivated, with China followed by the US, the biggest offenders. Like most countries, New Zealand would have information of interest, Dr Wolfe said.
If it was weapons-related, Chinese hackers would relay it to the military and intelligence sectors. But the GCSB was already sanctioned to combat this.
