“Witness Phil Zullo, who was driving northbound, says he first noticed the commotion when he saw police taking down a male suspect.”
Seems to be a certain lack of information there, isn’t there?
On Twitter there are some post attack videos where the van and the streets are shown. I don’t see how this is an accident unless someone was really drunk and then why would they have rented a van? It’s a business area with huge streets.
