Not the OP but at this level (a trillion dollar company) there’s definitely a third-party involved. I don’t particularly see anything wrong with that per se (I kind of see as “wrong” the part where we have three or four companies which are worth close to one trillion or more, but that’s another discussion), it is just a translation of the “checks and balances” thing from the party- and democracy-level to the corporate level (which corporate level might use parts of the old system for itself, in this case presumably the AG office). It’s not an ideal situation if you compare it to what the Founding Fathers might have desired but it is what it is.

I broadly agree with what you’re saying, but I think it’s misleading to sum it up as a lack of corruption. This kind of thing is exactly why Google would be hesitant to give up documents; they know that for many people on the other side of the table, the primary mission is hurting Google rather than upholding the law.
