Mubin Shaikh is one of the few people in the world to penetrate an Al Qaeda-inspired terror cell.

Shaikh - author of the new book "Undercover Jihadi" - appeared on "Fox and Friends" this morning in the wake of the brutal terror attacks in Paris.

Shaikh shared his inside perspective on the road to radicalism which led to brothers Cherif and Said Kouachi attacking the Charlie Hebdo offices.

He said all the evidence points to the brothers having trained with and been inspired by Al Qaeda in Yemen.

According to Shaikh, first, ear witnesses to the attack heard them actually say they were associated with Al Qaeda in Yemen. Second, they reportedly trained in Yemen and Said was definitely there for some time. Third, authorities found Al Qaeda in the Arabian Peninsula (AQAP) flags in the brothers' car. And fourth, Al Qaeda leader Anwar al-Awlaki had previously called in "Inspire" magazine for jihadis to target cartoonists.

"Al Qaeda is different from ISIS. Al Qaeda is more deliberate. This was a targeted killing, as opposed to what, for example, ISIS would like to do, which is randomly targeting civilians wherever they are," Shaikh said.

He explained that's why the Kouachi brothers specifically went after satirical magazine Charlie Hebdo, which they believe insulted their religion.

As for how to stop terror attacks like these, Shaikh said, "It really does come down to human intelligence ... good old fashioned police work."

"We're losing. We're not doing enough and we're not doing it in the right timeframe. We're still caught up in too many discussions. There is a lot of bureaucracy that prevents operators from doing what they need to do," Shaikh said.

What effect will this attack have on terror cells around the world? Brian Kilmeade asked.

"They're emboldened by it. Media gives terrorism a longevity it might not otherwise enjoy," Shaikh said. "It's not about the amount of people killed. It's about the amount of people watching."
