So from quickly reading up on this it looks like the CIA have access to pretty much all major tech from Microsoft, Google etc and can also do some pretty mental things on a global scale like take your fingerprint from your iPhone etc.
Essentially a roided up version of the NSA with no oversight whatsoever.
It sounds like the plot from a James Bond film except you would expect this from some tinpot billionaire terrorist, not an arm of the government.
And people are defending this why? The CIA has no remit to spy on me.
