“Laws that forbid the carrying of arms…disarm only those who are neither inclined nor determined to commit crimes… Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.” (Quoting Cesare Beccaria)
A statistic that is almost never discussed in conversations about 2nd Amendment rights is the number of attempted criminal attacks that are thwarted because private citizens are armed and prepared to defend themselves.
Wikipedia states that In 1993, Dr. Gary Kleck, Florida State University criminologist, won the Michael J. Hindelang Award from the American Society of Criminology for his book Point Blank: Guns and Violence in America (Aldine de Gruyter, 1991). He has testified before Congress and state legislatures on gun control proposals. His research was cited in the Supreme Court’s landmark District of Columbia v. Heller decision, which struck down the D.C. handgun ban and held that the Second Amendment protects an individual right to keep and bear arms.
