The Trail of Tears.
Following the Indian Removal Act of 1830, the United States government forcibly relocated thousands of Native Americans, removing them from their ancestral homeland. Many of these people died from exposure and starvation. The months-long journey (often made on foot) included not only Native Americans (including those who had gained citizenship) but some European Americans who married into Native American tribes as well as African slaves.
Japanese Internment Camps
Following Japan’s attack on Pearl Harbor in 1942, the United States government imprisoned more than 100,000 Japanese-Americans in internment camps, 62% of whom were citizens. The last camp did not close until 1946, a year after the end of World War II
From the 1950s to the 1970s, the US government conducted mind control experiments. These experiments included administering LSD to mental patients, prisoners, drug addicts and prostitutes, frequently without their knowledge.
The Tuskegee syphilis experiment was conducted from 1932 to 1972 by the U.S. Public Health Service. In the study, 600 impoverished African-American sharecroppers were told they were receiving free health care from the government. While they did receive medical care and food, the program was a cover up for a study of the progression of syphilis. The men were never told they were suffering from the disease and treatment was never provided and patients were even prevented from receiving any.
In 1927, the U.S. Supreme Court upheld a Virginia law which allowed for the mandatory sterilization of mental patients in state institutions. In 1972, United States Senate committee testimony revealed that at least 2000 involuntary sterilizations were performed on African American women on welfare who were threatened with an end to their benefits if they did not comply. The sterilizations were funded by the U.S. Office of Economic Opportunity.
There are many, many more stories of horrible acts perpetrated by the U.S. government against its citizens and against humanity as a whole. Do you still think the NSA isn’t something to worry about?
