When Officers Kill, Redress Is Rare, Review Shows Reuters The death in Minneapolis on Monday of George Floyd, the black man captured on video pleading for his life as a white police officer kneeled on his neck, has prompted three nights of protests, at times giving rise to violence, arson and looting. It has also again trained a national spotlight on a perceived lack of police accountability for violent encounters with the American public. The issue ignited in 2014 with the shooting death of Michael Brown, a black teen, by a white police officer in Ferguson, Missouri, which triggered angry protests. Since then, the "Black Lives Matter" movement -- sparked by the killing of black teen Trayvon Martin by civilian George Zimmerman in Florida in 2012 -- has become closely associated with critiques of overly aggressive policing, particularly against black people. Heightened public awareness, enhanced by the increasing prevalence of cellphone video, has kept the issue front and center through a series of incidents that have made national headlines in recent years. In another incident this year that has led to renewed unrest in the wake of Floyd's death, police in Louisville, Kentucky, killed Breonna Taylor, an emergency medical technician, on March 13 while executing a search warrant. Shielded from settlements In the majority of cases, Reuters found, police and the localities that employ them are largely shielded from having to pay financial settlements to victims or their grieving families by "qualified immunity," a legal concept developed by the U.S. Supreme Court that gives wide latitude to government employees when they act in the line of duty. The defense increasingly protects cops even when courts have determined that the officers violated a victim's civil rights, the investigation showed. One exception, however, is high-profile cases like those of Michael Brown that gain national attention. These cases are often outliers, resulting in generous settlement offers, and sometimes even criminal charges, before police have any recourse to claiming qualified immunity. Here is a summary of some of those cases and their outcomes: Michael Brown, a black 18-year-old killed by a white police officer in Ferguson, Missouri, in 2014. Settlement: $1.5 million. Criminal charges: None. Eric Garner, a black man who died after repeatedly crying "I can't breathe" while placed in a chokehold by a New York City cop during an attempted 2014 arrest. Settlement: $5.9 million. Criminal charges: None. Tamir Rice, a 12-year-old black boy who was holding a toy gun when shot dead by a Cleveland, Ohio, police officer in 2014. Settlement: $6 million. Criminal charges: None. .
