Target: St.Louis in only an hour or so delivers a powerful info packed message about a little known part of US history, the deliberate spraying of radiological material on two neighborhoods in a big city that were 70-80% African American residents.The documentary gives some background on a similar experiment previously done with some notice given in Minneapolis but then explains how the powers that be decided the next time to conceal what they were doing.Background is also provided on the role the US played after WWII in prosecuting the Nazis for such projects in which scientific experiments were done on unwilling subjects and how the US set up a code (which they then later violated) to prevent this kind of thing from happening again.Besides talking heads from St Louis and several well informed scholars the film uses a rich assortment of clip materials from other documentaries to make its case about racist and Nazi style behavior by our own political, business and even academic leaders, a visit to prestigious Stanford University reveals that college's shameful role in collaborating, which contemporary authorities try to cover up.See this program if you can, but be prepared to be profoundly depressed by the story it tells.
