I hear ya but the way it's usually done is you are only given options to walk away if you provide a benefit.. These could be the same people required to testify in the future.
Would much rather have bigger fish fry. Even if there are 100000000 documents indicting them for whatever they did… the general public is so brainwashed there will need to be testimony or there wouldn't be a need for us to begin with.
Documents can be fabricated. People facing the end of the rope are a little more believable. And as q has already alluded… some of these people may have been unwilling.
The money is being attacked via sa.. and exposure of the fake charities… and now the lower level back channel meddlers are being dealt with.
It's how you take down the mafia as well. Block their funds then remove their thugs from the street.
Can you imagine the psychology too?
It almost makes other "low level assets" inaccessible as you wouldn't know who is compromised… and that's typically why the mob will start taking people with knowledge out.
