It had not occurred for me for a minute to think of Newsome as a "single activist." Her brave step seems so obviously to arise out of organized demands, out of the wonderful eruption of justice energy that is the Black Lives Matter movement. She was undoubtedly aware of a community of sisters and brothers who would have her back. That posse would leverage the resources to support her. Her life matters.
Now Loomis is of course right that lonely acts can sometimes prompt vast movements. But lonely acts will often -- usually -- sink without a ripple. What's hard is to predict which actions will make enduring waves. What Newsome did certainly amplified a cresting tide already in motion. She's won an honored place in the long river of resistance -- but she is certainly not alone.
