Even if your gut tells you guns cost society far more than you thought, these numbers will shock you. In collaboration with Miller, Mother Jones crunched data from 2012 and found that the annual cost of gun violence in America exceeds $229 billion. Direct costs account for $8.6 billion—including long-term prison costs for people who commit assault and homicide using guns, which at $5.2 billion a year is the largest direct expense.
