Black Panthers Fred Hampton, 21, and Mark Clark, 22, are gunned down by 14 police officers as they lie sleeping in their Chicago, Illinois, apartment. About a hundred bullets had been fired in what police described as a fierce gun battle with members of the Black Panther Party. However, ballistics experts later determined that only one of those bullets came from the Panthers’ side. In addition, the “bullet holes” in the front door of the apartment, which police pointed to as evidence that the Panthers had been shooting from within the apartment, were actually nail holes created by police in an attempt to cover up the attack. Four other Black Panthers were wounded in the raid, as well as two police officers.

President George H.W. Bush orders 28,000 U.S. troops to Somalia, a war-torn East African nation where rival warlords were preventing the distribution of humanitarian aid to thousands of starving Somalis. In a military mission he described as “God’s work,” Bush said that America must act to save more than a million Somali lives, but reassured Americans that “this operation is not open-ended” and that “we will not stay one day longer than is absolutely necessary.” Unfortunately, America’s humanitarian troops became embroiled in Somalia’s political conflict, and the controversial mission stretched on for 15 months before being abruptly called off by President Bill Clinton in 1993.

On December 4, 2009, 22-year-old American exchange student Amanda Knox is convicted of murdering her British roommate, Meredith Kercher, in 2007 in Perugia, Italy.

The sensational, high-profile case raised questions in the United States about whether Knox, who always maintained her innocence, received a fair trial. Then, in October 2011, in a decision that made international headlines, an Italian court reversed the murder convictions of both Knox and Sollecito and they were freed from prison.
