The weapon used by a 20-year-old man to murder 20 children and six adults in a Connecticut grade school could be obtained as easily as visiting a local discount store.
The tragedy prompted an immediate call for the nation to revisit gun control legislation. Others suggested that an answer might actually be less gun control, arming more of our friends and neighbors to defend the community against killers when they strike.

Political leaders can immediately address how to make weapons of mass murder less accessible, through requirements for registration, background checks or mandatory training.

Official ratings organizations make no effort to inform the public about how many bodies are dispatched in movies or video games or are alluded to in lyrics to hard driving rap rhythms.
