Spring has hardly arrived, and already the season has seen the deaths of two black men, both shot by law enforcement when they were unarmed and posing no serious threat. Sacramento's Stephon Clark was shot six times in the back, and lay bleeding in his grandparents' backyard for several minutes while the officers who shot him looked on from a safe distance. It turned out that his "gun" was only a cell phone. Saheed Vassell was shot 10 times by New York City officers, as he held out the metal pipe that they mistakenly took for a gun. Vassell suffered from bipolar disorder, and neighbors described him as friendly and harmless.
