Crime

Eight in 10 Americans said in 1999 that Columbine was not an isolated incident, but rather a sign that something was "seriously wrong" in the U.S.

Americans' views on how the justice system is handling crime have changed in the past decade. Less than half (45%) say it is "not tough enough," down from 65% in 2003.

Long before social media, the internet or video games entered the scene, Americans viewed comic books as a dangerous, new corrupting influence on U.S. youth.
