These are good points, well said.

I agree. Insert great power/responsibility saying.

They always seem to go off the rails.

I would be in favor of mandatory disclosure (though, this would be extremely difficult and costly). I imagine anytime a government privilege was used, especially when behind closed doors, and reviewed by "...the proper oversight officials...", whoever that means, I would rather like the governments to prove it.

I would support an idea that by law, it all has to be documented, and after a reasonable amount of time after the prosecution is complete, they have to disclose everything they did, all the snooping, etc. With redacted private information of course for unrelated people.

This is fairly unreasonable/unrealistic. But for me, if you could see all the cases where a government invaded privacy and link it to all to nothing but legitimate uses, it might help restore some faith/trust in officials.
