Here's the brutal part: a vehicle can kill faster than a gun can aim. DHS claims the SUV was used as a weapon, and if an officer reasonably believes he's about to be run over, the law does not demand he flip a coin with his life. Reuters also notes video details people interpret differently, including the car's wheels turning away and questions about timing. That is exactly why this cannot be decided by social media edits or political slogans. Release the full footage, the training record, and the DHS use-of-force language, and let prosecutors argue it in daylight. And if activists want fewer tragedies, stop turning the street into a game of chicken.
