You cited Wikipedia, and you haven't cited a single source for any proposition other than the one you were specifically wrong about.

Deliberate obtuseness. The obvious implication of the reference to gangster films is that anyone who has even a passing familiarity with protection rackets knows that harm from the racketeer is not the only threatened harm. The third sentence of the Wikipedia entry you mentioned confirms this: "Through the credible threat of violence, the racketeers deter people from swindling, robbing, injuring, sabotaging or otherwise harming their clients." That means that the analogy between the CIA and a protection racket is perfectly tenable—in the parlance of your Wikipedia entry, a "broader protection racket" rather than a "pure extortion racket."
Not sure how to spell it out any clearer than that. I'm not implying you're getting concepts wrong. You got them both wrong.
