A growing movement is urging media organizations to avoid naming the gunmen in mass shootings.
The idea is to avoid inspiring more shooters who seek infamy and notoriety.
The notion took root in the years after the Columbine attack. The 1999 Colorado assault continues to motivate mass shooters, including the two men who this week stormed their former school in Brazil, killing seven people.
The gunman who killed at least 50 people Friday at two mosques in New Zealand was said to have been inspired by the man who in 2015 killed nine black worshippers at a church in Charleston, South Carolina.
