Celebs, some directly affected by the Terminal 3 tragedy, are taking to Twitter.
Stars are tweeting about the tragedy unfolding on their turf of tarmac, LAX.
Some seem grateful and indignant, such as Lisa Rinna:
"Shooting at LAX Virgin America so scary!"
"HH (husband Harry Hamlin) and I were just flying virgin America this week through LAX"
"So now what #Homelandsecurity? #lax #shooting"
"So now what happens BEFORE you get to the TSA agents and security at all airports?"
Others are getting angrily political, including Patton Oswalt:
"Let's see if the gun rights advocates can wait a decent interval before spouting their bullsh — oops, never mind. #LAX"
Andy Cohen got contemplative:
"#TSA agents have impossible jobs to begin with.. Awful."
There are those in the thick of it, such as Nick Jonas:
"Landed at LAX at (sic) to the news that there was a shooting in the terminal my plane was supposed to deplane at."
"Currently waiting on the plane in a remote parking area. I am safe. Praying for the victims of this shooting."
And then there's James Franco, who got profane and pensive — in a selfie shot from inside a plane:
"At #lax Some (bleep)bag shot up the place."
