Since Friday morning, a police officer was gunned down in Memphis, leaving four children without their mother. Two officers were killed outside a grocery store in Topeka. A woman was shot and killed inside a Las Vegas casino. Three people were shot inside an Alabama hospital. A four-year-old was caught in a drive-by in Missouri and taken off life support just yesterday. Each one of these Americans was a victim of the everyday gun violence that takes the lives of more than 10,000 Americans every year — violence that we cannot accept as routine.
