Furthermore, we must not forget that even the "guiltiest" and scummiest men deserve the full protections the law affords. Shortcuts around due process cannot be justified by saying, correctly or not, "This guy is a total sleeze and guilty as hell".
Also due process was followed as far as I know. Read the indictment. There was enough evidence to have his assets seized just like any other business if there is enough evidence to believe there are ongoing illegal activities. And yes the NZ government did agree to this also, otherwise his arrest in NZ wouldn't have happened.
The issue specifically is the apparently illegal search warrant/raid. Well, actually to be honest that by itself does not particularly disturb me, mistakes are always made. The issue is the number of people I see on HNs dismissing what they see as technicalities because they know he is guilty.
The justice system is designed to afford protections to the obviously guilty because without that, it is no different than mob justice.
