aw enforcement officials in San Bernardino and Los Angeles may have investigated Syed Farook one week before the shooting on the community development center on December 2, 2015, that left 14 dead and 17 injured, according to a review of police communications immediately following the attacks. Federal and local authorities have insisted that neither of the attackers had aroused suspicion before the assault earlier this month and that both Syed Farook and his wife, Tashfeen Malik, were unknown to law enforcement and US intelligence. But conversations between law enforcement officials in the hours after the shootings leave a different impression.
