Last Sunday, Cleveland Browns wide receiver Andrew Hawkins drew national attention for wearing a shirt with the words "Justice for Tamir Rice and John Crawford" printed on it. Hawkins's shirt referred to two recent shootings by police in Ohio. Tamir Rice was a 12-year-old child who was killed by police despite the fact that a 911 caller said the gun Rice had was probably fake (the caller was right—it was a toy pellet gun). John Crawford was a 22-year-old man who was walking with a BB rifle in the toy gun aisle of a Wal-Mart when he was shot and killed by police. There are reasons to be concerned about the legitimacy of police actions in each case, writes Chris Edelson.
