How many crimes are stopped by gun owners?

According to the FBI, between 1.6 to 3%

According to Dr. Gary Kleck, criminologist at Florida State University in Tallahassee and author of "Point Blank: Guns and Violence in America," a book used by many in the gun debate, 800,000-2,500,000 crimes are stopped by guns each year. The numbers are from different studies.

Interesting Statistics:

There were over 19,000 deaths by accidental drug overdose in 2004. The majority of these deaths were from prescription drugs, not illegal drugs. Banning prescription drugs makes as much sense as banning guns.

Regarding accidental shooting deaths per year, that number is in the 14,000-17,000 range. Over 100,000,000 guns are owned in America.
