A longtime FBI agent warns the City of Dallas could be a top target for a terrorist attack and North Texas law enforcement needs to be prepared.

A federal report on terrorism – to be released Thursday - predicts a nuclear or biological attack within the U.S. sometime over the next five years.

Danny Defenbaugh, the former Dallas FBI director, says North Texas needs to take the report seriously because there is reason to believe the area could be a prime target.

Defenbaugh has been operating a private security consulting firm since retiring. He says terrorists might choose North Texas for an attack for multiple reasons.

For one reason, Exxon-Mobil’s headquarters is based in Irving.

Another reason is because President Bush will reside in Dallas when he leaves office, and his library will be built at SMU.

Defenbaugh told KRLD radio that “anytime you have a former president or you have the former president’s library that’s going to be established, I think that always adds to another vulnerability or another risk that has to be assessed as far as a target.”

He also praised the North Texas joint terrorism task force and said it has a good history of intercepting threats.
