Funding the Tuskegee Expertiment...

How was it possible for the government to fund such a horrible expertiment without anyone knowing of it. Are they that good at hiding things? This expertiment should have not went on as long as it did. Matter of fact, it should have not went on at all. The individuals who were responsible for funding and operating this expertiment should have faced more harsh consequences for what they did. I can not help but to think that if our government could get away with hiding what was truly going on in this expertiment, what else are they hiding?
