Even more so, the world governments did not sanction them to break international law. Yes, their formation was legal, but they have already went beyond their legitimate purpose.
The world governments are at fault, in the sense that they appeared to have not left ANY observers in place to ensure A-Laws is actually doing their jobs. For all they know, A-Laws could be spending all their money hiring strippers and plan drunken orgies, and the world governments would still pay for the expenses without looking at them.
There is nothing legal about A-Laws, if they are not held accountable for their actions. "Government sactioned" assumed that the government is held responsible if things go wrong, and things have undoubtedly gone wrong.
