John Key may make promises about how future Prime Ministers will issue warrants, he may make promises about how the law will be interpreted – but he’s not in a position to make those promises. Similarly his promise that he’ll resign if there’s mass surveillance of New Zealanders is empty if it doesn’t happen / isn’t found out on his watch.
He can’t guarantee what Prime Ministers after next year will do, as it may not be him. He won’t be the lawyer or judge interpreting in court the legality of GCSB actions.
The people who will be making those decisions say the wording of the law is bad, so he should listen to them. These important laws that impinge on our freedoms should be passed with much more consensus, not by 1 vote majority. Accepting democracy means accepting that even if you feel you are right, other people’s viewpoints (especially those with more relevant experience than you) are valid and must be taken into consideration, not dismissed.
Now, which government MP is willing to stand up for Democracy?
[Also, John Banks - have you checked your party's philosophy recently? We all know you're a ring-in Nat poodle not a true Act believer, but I suspect there's more than a few in ACT who find this massive erosion of privacy somewhat disturbing...]
