25 Statistics That Reveal Everything You Need To Know About The U.S. Firearms Industry

On Friday, December 14, a gunman entered an elementary school in Newtown, Conn., and shot and killed 26 people including 20 children. Earlier that same week, an Oregon man shot three people at a shopping mall before taking his own life. A few months before that, a gunman entered a movie theater in Aurora, Colo., and left having taken 12 lives.

Tragedies such as these have raised serious questions about a firearms industry growing larger and more powerful everyday.
