The days following a pickup truck attack that killed 14 people have brought second-guessing and finger pointing over whether additional safety measures could have prevented or mitigated the carnage.

The attack on Bourbon Street "struck me as being particularly reminiscent of ISIS advice,” said Joshua Fisher-Birch, a researcher at the Counter Extremism Project.

Cameras captured the events leading up to the death of the suspect, Shamsud-Din Jabbar. Jabbar had driven his white F-150 around a police car blockading the entrance of Bourbon Street, the city’s most famous thoroughfare, and plowed into revelers about 3:15 a.m. New Year’s Day, killing 14 and injuring dozens.

Before Shamsud-Din Jabbar attacked Bourbon Street in New Orleans, the FBI says he researched the city, reading up on recent shootings and a vehicle attack in Germany.

The FBI has found no evidence that a late-October visit to Tampa by the man behind a New Year’s Day terrorist attack in New Orleans was related to “criminal intent,” the agency announced Wednesday. It remains unclear exactly why Shamsud-Din Jabbar came to Tampa about nine weeks before he drove a rented truck through a crowd of people in New Orleans’ French Quarter and engaged in a fatal gunfight with police.

The FBI investigated personal devices belonging to the suspect of the Bourbon Street attack, and found eerie evidence within suspect's search history.

The FBI provided an update Tuesday on the New Year's Day attack in New Orleans, revealing new information about the attacker's online search history as well as releasing a photo showing him walking in the city just weeks before the rampage that killed 14 people.
