FBI dropped the ball . . . again.

Via NY Times:

Two years before the bombings that Ahmad Khan Rahami is suspected of carrying out in New York and New Jersey, his father told the police that his son was a terrorist, prompting a review by federal agents, according to two law enforcement officials.

The father, Mohammad Rahami, in a brief interview on Tuesday, said that at the time he told agents from the Federal Bureau of Investigation about his concern, his son had just had a fight with another of his sons and stabbed the man, leading to a criminal investigation.

The father made the statement about his son being a terrorist to New Jersey police in 2014, when Mr. Rahami was arrested after a domestic dispute and accused of stabbing his brother.

The information was passed to the Joint Terrorism Task Force led by the Federal Bureau of Investigation in Newark. Officers opened what is known as an assessment, the most basic of F.B.I. investigations, and interviewed the father, who then recanted.
