On Wednesday, Breitbart reported that the driver of the truck that drove into the crowd in New Orleans was a U.S. Citizen and an Army veteran who carried an ISIS flag in his truck.

The article reports:

The suspect accused of plowing a pickup truck through a crowd on Bourbon Street in New Orleans, killing 15 and injuring at least 30 on New Year’s Day, is named Shamsud-Din Jabbar, according to the Federal Bureau of Investigation.

The article includes a statement by the Federal Bureau of Investigation (FBI):

The subject has been identified as 42-year-old Shamsud-Din Jabbar, a U.S. citizen from Texas. He was driving a Ford pickup truck, which appears to have been rented, and we are working to confirm how the subject came into possession of the vehicle.

An ISIS flag was located in the vehicle, and the FBI is working to determine the subject’s potential associations and affiliations with terrorist organizations.

Weapons and a potential IED were located in the subject’s vehicle. Other potential IEDs were also located in the French Quarter. The FBI’s special agent bomb technicians are working with our law enforcement partners to determine if any of these devices are viable, and they will work to render those devices safe.

At what point (and how) was this person radicalized? It is disturbing to me that the man was an Army veteran. Was he a radical who joined the army without revealing his views or was he radicalized during or after his service? I think it would be helpful to know that.
