Former CIA Deputy Director Phillip Mudd on Sunday told Fox News that Boston bombing suspect Dzokhar Tsarnaev should be charged as a murderer because the crime looked more like the 1999 massacre at Columbine High School in Colorado than an attack planned by al Qaeda.

During an interview on Fox News Sunday, host Chris Wallace asked Mudd if there were signs that al Qaeda was behind the Boston Marathon bombing.

"The only fingerprint I've seen might have possible have been ideology, but not operations," Mudd explained. "But every step of the way here was pretty rudimentary. For example, if you look at some of those initial photos, you've got a kid with a hoodie and a cap. If he wants to obscure himself, the hoodie goes on, the cap forward."

"If he had operational training, I want to know who did it because they were amateurs."

Mudd added that he feared that people were being too quick to categorize the crime as terrorism.

"This looks more to me like Columbine than it does al Qaeda," the counter terrorism expert observed. "Two kids who radicalized between themselves in a closed circle go out and commit murder. I would charge these guys as murders, not terrorists."

Wallace pressed Mudd on how he could dismiss the fact that Dzokhar Tsarnaev's brother, Tamerlan Tsarnaev, spent six months in Russia "where there are a lot of radicals."

"I'm not writing that off," Mudd insisted. "What I'm saying is we want to categorize this... with a simple term, and at looking at the psychology of clusters like this -- which I did for 20 years -- the psychology is not that simple. It's two kids who decided, for whatever ideology, that they wanted to commit murder. And the murder piece is significant as the terrorism piece."
