The incident on Bourbon Street saw a gunman drive a truck into a crowd, resulting in 14 fatalities and over 30 injuries.
Following previous terrorist attacks, New Orleans had implemented road-blocking bollards to enhance safety during events, particularly on Bourbon Street.
At the time of the attack, 11 of the 16 bollards were non-operational and undergoing repairs, which officials cited as a major concern.
New Orleans police leadership faced backlash for a lack of knowledge about additional safety barriers that could have been deployed during the incident.
Former homeland security director, Aaron Miller, expressed regret that protective measures were not in use during the attack, highlighting the city's prior awareness of potential terror risks.
