Even "egomaniac jerks" are entitled to due process of law.
This debacle was simply Mr Key doing his obedient poodle routine for Uncle Sam, and over-ruling rightful Police objections as to the (il)legality of the process. Crown Law Office assisted the minister in charge of making us look like a banana republic (aka "Minister of Justice") with pushing the operation through against Police objection.
I'd be interested to know whether the "SWAT on steroids" approach was Police making a point about the excessive stupidity of the operation, or whether the Politicians managed to find enough nutters within Police to put together what they must have presumed would impress our Imperial Masters. (Sadly, it's more likely the latter.)
By the way, how many millions in damages do you estimate we'll we be paying out to the "egomaniac jerk" after the courts toss this little operation onto the scrapheap alongside the other recent government over-reach cases? Do you think Uncle Sam will reimburse us?
More suspicious developments:
Nah, no political string-pulling in this case... It's all that evil fat foreigner being an evil-doer and panicking Hollywood's geriatric egomaniacs.
