the data is thus all available to them and they can choose to 'monitor' it

Intelligence agencies do not 'choose' to monitor anything. They must get a Court Order (effectively a warrant) to read private documents. You can look all this up, if you're really interested in how it works. It's all public information.

To which 'war crimes' were you referring (careful, I'll want evidence, not hearsay)

I'm not actually all that authoritarian. I just understand why there must be secrets (that's where the word 'secretary' comes from) and that Governments do things that individuals never would, because they understand that the alternative is worse. To not 'play the game' is like Socialism - its always going to fail because it only takes one person to not play it and the whole thing falls apart for those who do play by the rules.
