Was the New Orleans incident a terrorist attack? FBI's definition is...

The New Orleans mass killing on Bourbon Street saw a vehicle ploughing into a crowd, resulting in multiple deaths and injuries. Initially, FBI labeled it non-terrorist, but later reclassified it as a terrorism act, investigating the use of IEDs and the attacker's possible ideological motives. Initially, FBI special agent Alethea Duncan said it was not a terror incident. It was an incident that involved IEDs and the agency was probing whether those IEDs were viable or not.
