trigger and who was injured at the other end of it if they know. >> it shouldn't be surprising to any viewers, there now has been a ground stop at l.a.x. meaning no flights are coming in or taking off as this incident continues. and we see law enforcement, we see fire and rescue operators on the scene, as well. it looks like they're gearing up for something protracted. you can see some temporary structures now being established there. unclear what has happened. we did see some wounded folks evacuated from terminal 3 at l.a.x. a little while ago. we had video of one individual wearing a blue shirt. you could make south some blood on that shirt, as well. we don't know if that was a tsa uniformed personnel officer or anyone or if it was just someone else wearing a uniform or wearing an outfit similar to what the tsa wears, but it's clear that this is -- they're gearing up for a big operation.
