Although originally projected to last 6 months, the study actually went on for 40 years.

What Went Wrong?

In 1932, the Public Health Service, working with the Tuskegee Institute, began a study to record the natural history of syphilis in hopes of justifying treatment programs for blacks. It was called the "Tuskegee Study of Untreated Syphilis in the Negro Male."
The study initially involved 600 black men – 399 with syphilis, 201 who did not have the disease. The study was conducted without the benefit of patients' informed consent. Researchers told the men they were being treated for "bad blood," a local term used to describe several ailments, including syphilis, anemia, and fatigue. In truth, they did not receive the proper treatment needed to cure their illness. In exchange for taking part in the study, the men received free medical exams, free meals, and burial insurance. Although originally projected to last 6 months, the study actually went on for 40 years.

In July 1972, an Associated Press story about the Tuskegee Study caused a public outcry that led the Assistant Secretary for Health and Scientific Affairs to appoint an Ad Hoc Advisory Panel to review the study. The panel had nine members from the fields of medicine, law, religion, labor, education, health administration, and public affairs.
The panel found that the men had agreed freely to be examined and treated. However, there was no evidence that researchers had informed them of the study or its real purpose. In fact, the men had been misled and had not been given all the facts required to provide informed consent.
The men were never given adequate treatment for their disease. Even when penicillin became the drug of choice for syphilis in 1947, researchers did not offer it to the subjects. The advisory panel found nothing to show that subjects were ever given the choice of quitting the study, even when this new, highly effective treatment became widely used.

In this ruling, the U.S. Supreme Court stated that slaves were not citizens of the United States and, therefore, could not expect any protection from the Federal Government or the courts. The opinion also stated that Congress had no authority to ban slavery from a Federal territory.

Activist jailed and beaten

Hamer became a SNCC field secretary in early 1963. A few months later, she attended a citizenship training school sponsored by the Southern Christian Leadership Conference (SCLC) in Charleston, South Carolina, to learn how to teach her neighbors about the benefits of citizenship. On the bus trip home in June, the bus made a rest stop in Winona, Mississippi. Annelle Ponder of SCLC, who was traveling with the group, said that three or four of the people went in to the café to be served. They sat at the counter but the waitress refused to serve them. A highway patrolman came from the rear of the café and tapped some of the group on the shoulder with his billy club, saying, “Y’all get out — get out.” Ponder reminded him it was against the law to refuse them service but he said, “Ain’t no damn law, you just get out of here!”
On the way back to the bus, Ponder wrote down the license number of the patrol car and at that, the patrolman and police chief came out of the restaurant and put the cafe group under arrest. As that was occurring, Hamer got off the bus to see whether the rest of the group should go on to Greenwood. The police chief arrested her as well. Later the police had two other black prisoners beat Hamer and 15-year-old June Johnson, who would not say “sir” to the men. In a trial later that year, an all-white jury acquitted the law officers. Hamer recalled, “After I got out of jail, half dead, I found that Medgar Evers had been shot down in his own yard.”

A Nassau Bay police officer has been suspended with pay after former astronaut Mae Jemison accused him of twisting her wrist and slamming her to the ground during a traffic stop.
The Chicago native, who in 1992 became the first black woman to fly in space, complained to Police Chief Robert Holden that Officer Henry Hughes III physically and emotionally mistreated her when she was arrested on a speeding warrant Saturday. 
The department said Hughes has been suspended with pay pending an investigation by the department's internal affairs division.
According to Jemison's complaint, Hughes stopped her for an illegal turn. After learning of an outstanding warrant for failing to pay a speeding ticket, the officer told Jemison she was under arrest.
Her attorney, Rusty Hardin, said Jemison threw down her car keys in disbelief. When the officer started to handcuff her, she reached down to pick up the keys.
"When she does that, he grabs her left hand, knocking her wallet and paper out of it, twists her wrist and throws her arms up behind her back" before throwing her down on the road, Hardin said.

On Tuesday, the arrest warrant for the incident was released, detailing state trooper Brian Encinia’s version of events.
According to the officer, Sandra  Bland — a 28-year old African American woman — was pulled over for failing to signal a lane change and he “had Bland exit the vehicle to further conduct a safe traffic investigation.”
“Force was used to subdue Sandra  Bland to the ground to which Bland continued to fight back,” he added.
Sandra Bland was charged with assault on a public servant then booked in the Waller County Jail, where she later died.
