What Are The Chances of Becoming A Homicide Victim?

With all of publicity surrounding crime statistics, it is easy to get a misleading impression about the risks that homicides pose. Recent data from the Centers for Disease Control can provide a factual basis from which to assess the real risks.

What is a Mass Shooting? What Can Be Done?

In the United States, there are several different, but common, definitions of mass shootings. The Congressional Research Service defines mass shootings, as multiple, firearm, homicide incidents, involving 4 or more victims at one or more locations close to one another. The FBI definition is essentially the same. Often there is a distinction made between private and public mass shootings (e.g., a school, place of worship, or a business establishment). Mass shootings undertaken by foreign terrorists are not included, no matter how many people die or where the shooting occurs.
