I recently read this opening paragraph in a story I found in a back-issue of ESPN The Magazine: “Death is delivered pink. The lethal liquid that's injected into the jugular of broken-down racehorses is always colored. That way, a vet can find it quickly. That way, it can't be mistaken for any other drug. There's no time for fumbling when a 1,200-pound animal has suffered a catastrophic injury -- a broken leg or a fractured ankle.”
