Ex FBI agent on Brussels attacks: ‘We don’t know how big this is’
Don Borelli, a former assistant special agent with the FBI, says “we don’t know how big this is” and the prospect of future attacks is “very scary.” He thinks the attacks were carefully planned rather than being a quick response to the arrest of Paris terror suspect Salah Abdeslam, though the timetable may have been moved up in the wake of Abdeslam’s arrest.
