Investigators favor domestic theory

The Boston Marathon bombings bear the hallmarks of anti-government domestic terrorism — not foreign, experts said yesterday.

They cited the lack of Internet “chatter” or a claim of responsibility, the crude nature of the explosives and the timing.

“The month of April is very significant,” said Harvey Kushner, author of the “Encyclopedia of Terrorism.” He noted that the 1993 Waco siege and 1995 Oklahoma City terror bombings occurred on April 19.

“On top of that, it happened on Patriots Day. That’s a message and a half,” he said.

American University terrorism expert Brian Forst said it was “plausible” that the attack was carried out by a “right-wing terror group” such as a neo-Nazi or white-supremacist group. This coming Saturday is Hitler’s birthday, he noted.

Kushner said the bomb — a pressure cooker with ball bearings — had been used in Afghanistan and could indicate foreign terrorism.
