Chief Keef Silent Over Times Square Shooting

Chief Keef was mum as hell Saturday at LAX ... refusing to talk about someone who fired a shot at him earlier in the day across the country.

Our photog gently broached the subject ... someone took aim at Keef outside the W Hotel in Times Square around 6 AM Saturday. The shooter missed ... the bullet struck a hotel sign.

Cops are on the hunt ... they're looking for 2 men.

Keef's crew did their boss's talking for him, but didn't really clear up the situation.
