(CNN) -- As the story of the tragic Newtown, Connecticut, elementary school shooting unfolds, many people are pondering: Why has there been so much violence in the U.S. lately, and what can be done to stop it?
This year saw a mass shooting of movie theater patrons in Aurora, Colorado; the sentencing of Jared Lee Loughner on 19 counts, including murder and the attempted assassination of congresswoman Gabrielle Giffords; and the first overall rise in U.S. violent crime in nearly two decades. And as the world heard about the Connecticut school killings, many people took to social media to express their frustration.
