North Carolina Teen Indicted as Adult for San Diego Mosque Shooting

GoPro helmets were used to livestream the mosque attack, and three viewers watched the stream, including a woman living in the Eastern Time Zone.

Prosecutors say she livestreamed the attack using GoPro helmets, published the shooters' manifesto online, and even supplied a neo-Nazi patch worn by one attacker.
