The laws are still very unclear. Cells are still taken from people without consent - a lot of people don't realize it.

Often doctors didn't even tell you what was wrong with you. They just treated you, and sent you home.

Black patients were treated much later in their disease process. They were often not given the same kind of pain management that white patients would have gotten and they died more often of diseases.

The sort of thinking at the time was, 'Well, we're giving you access to medical care which you wouldn't otherwise be able to get, so your payment is that we get to use you in research.'

Christian Science has been enormously influential in our religious history, and the church is very powerful. It has won an extraordinary number of legal battles in this country. It has succeeded in passing a number of what are called 'religious exemption laws.'
