() Lone wolf attacks such as the targeted attack on a group of pro-Israel demonstrators in Boulder, Colorado, are extremely challenging to prevent, according to a former FBI analyst.

Javed Ali, a former FBI analyst and associate professor at the University of Michigan, joined ” Now” to discuss the attack.

“These are arguably the most difficult to stop from a law enforcement and counterterrorism perspective, because when you’re dealing with a single individual not connected to a foreign group or even a group or network inside the United States, they are literally operating under or on their own,” Ali said.

“Time and time again, we’ve seen in these types of loan offender attacks that people like (Mohamed) Soliman are able to plan methodically for a long period of time and then transition from being radicalized and angry to then springing into violent action.”

Soliman was arrested Sunday and is accused of attacking a crowd with a makeshift flamethrower. The Egyptian national.

According to court filings, Soliman said he wanted to kill all Zionist people and that he would conduct the attack again.
