Did they ask him to turn himself in?
I can't say I know what New Zealand's procedure for this actually is, but in the US, one of two things would occur in a white-collar case like this: The suspect would either surrender with his attorney at a prearranged time and place, or he would be arrested by a couple of officers who peacefully knock on his door.
Anything else would be seen as grossly excessive force, the fallout of which could easily involve ruined careers and political repercussions.
And I don't know who you're talking about that "idolizes" him. I don't. I actually have no particular opinion about him one way or another, only about the manner in which the case has been handled.
You're the one who seems to be taking things very personally.
