A database by The Associated Press, USA Today and Northeastern University shows that there have been 23 mass killings so far this year, claiming the lives of 131 people.

James Alan Fox, a criminology professor at Northeastern University in Boston, attributes the difference in media coverage to the nature of the attacks.

Nevertheless, these terms are often conflated, said James Alan Fox, a criminologist at Northeastern University.
