HOW LIKELY IS A BREAK-IN?
The Bureau of Justice Statistics estimated that in 2010 (the most current year for gathered data), more than 3.7 million household burglaries occurred. Of that number, a member of the house was at home more than 1 million times. As shocking as that is to hear, the number of actual violent altercations was more than 260 thousand times. It is important to pay attention to who comes in and out of your house. At least the victim knew 65 percent of assailants.
The FBI statistics list 430 homicides on average per year between 2003 and 2007. Statistically, you should have the advantage if you are armed, because the assailant was armed with a firearm in less than 11 percent of all burglaries. It is more likely they will have a weapon of a different sort, such as a knife. Over 40 percent of all burglaries are committed by an intruder armed with some sort of weapon.
