After 12 Monkeys [script], we somehow got into a whole thing about animal testing (necessary in some cases, maybe, but nonetheless horrendous, and almost certainly very rarely or never necessary) and ultimately into the fact that this sort of unethical testing has been done, quite deliberately, on humans.

I'm not just talking about the Nazis, either. It was done in this country, by our government, to its own citizens.

In both of the following two cases, racism was the accomplice.

The Tuskegee Syphilis Experiments
Radiation Experiments on Humans

There's a book on all this whose paperback edition that I'm very anxiously waiting for; it's called In the Name of Science.
