Gunman had an AR-15 rifle in a bag, took it out and began shooting, made his way through a checkpoint and continued his way down the hall in terminal three - officers went into immediate response not waiting for SWAT team (relatively new tactical strategy within last 5 years). Small cluster of officers engage the shooter right away to draw gunman's fire vs. firing into the crowd, speculate this is why so many lives were saved. City is on partial tactical alert - officers are not allowed to leave their shift - vacations for today are cancelled. Whitehouse Senior Staff have been briefed. 7 injured, 6 taken to hospitals - west side of LA - southbay curve, 105 century dumps out @ LAX - all standstill (parking lots). (per CBS LA) Airport shut down - people have nowher eto go.
