At least with the FDA I'm eating food and taking medicines that doesn't make me or the people around me sick all the time (as they did before the founding of the FDA).
With casinos it's the opposite. Their customers regularly lose their shirts. Maybe the games aren't rigged, maybe they are, as someone who regularly loses (as most gamblers do), they might as well be rigged and I would not be surprised if there was regulatory capture and the consumer would have no way to know.
You can't, but, at least in Las Vegas, the machines are under fairly strict protocols. If a customer makes a complaint, things get sealed and impounded almost immediately.
And, besides, if it ever got out that a casino was doing that, it would basically fold up overnight.
