It occurs to me that, in my understanding, the CIA is very explicitly forbidden by law from operating in the United States, for very obvious reasons.
Any assets they are paying in our national news media are therefore criminals, and liable to Federal arrest and prosecution, as are their handlers and anyone who can be shown to have known about this arrangement.
I figure at least a third of the people we see on TV would disappear if this happened. And something like it NEEDS to happen. We cannot go on with this madness, with this fog of egregious and shameless lies, forever.
That would be one legal remedy, consistent with the First Amendment.
