The man who carried out an attack on Bourbon Street in New Orleans early New Year’s morning visited the city twice in the months prior and used Meta smart glasses to film the street and plan out the attack,

Shamsud-Din Jabbar wore the same Meta smart glasses when he carried out his New Year’s Day attack, but there’s no indication he was recording, authorities said.

President Joe Biden and the first lady will visit the city Monday. The day also marks the start of Carnival that leads up to Mardi Gras.
