Both the lightning f150 used in the new orleans car ramming attack and the tesla cybertruck used in the car bombing at Trump Tower were rented via the Turo app, and police said video from the ramming showed suspects planting pipe bombs in the area before the ramming, which leads them to believe it was multiple terrorists involved. That's also reason to believe the two attacks were linked, but none of that is confirmed yet. The negative case would be the possibility it was two unrelated terrorist attacks, by two lone wolves, just coincidentally on the same day, and the guy who did the car ramming in new orleans (shamsud din jaffar ali baba over there) had planted the bombs, returned to his truck, then rammed into people and was killed before he could detonate anything (or they were duds)
But good chance this was multiple coordinated attacks by a terror cell of multiple people
