Latest terror attack reveals ISIS may be 'much, much bigger' than suspected

ISIS has claimed responsibility for Thursday’s terror attack in which a van plowed into a crowd of pedestrians on one of Barcelona’s most populated streets. At least 13 people were killed and dozens injured when the driver swerved back and forth across Las Ramblas, a wide boulevard with a pedestrian-only section down the center, and then slammed into a restaurant.

This latest tragedy adds Spain to the growing list of countries targeted in a series of terror-attacks using automobiles. Terrorists can travel especially easily between European countries because of European Union travel regulations.

"This seems like there is a massive, a huge multi-city cell and they are able to travel easily ... between each country," said Dana Loesch on today’s “Dana.” “How in the world does law enforcement fight something like this when [terrorists] can slip by so easily and undetected,” Dana asked of guest panelists, Doc Thompson, Kane Lightle, and Sara Gonzales.

“I don’t know how you track them like that, because it's not just them,” answered Doc. He added, “It’s the same type of attack now that’s become common. You run people over because everyone can get a car. This is the new norm.”
