LOS ANGELES (AP) - With so many celebrities passing through Los Angeles International Airport at any given time, there were several around this past Friday when a gunman shot up a security checkpoint. One TSA officer was killed. Some of them kept fans posted on their experiences through Twitter. James Franco used an expletive to describe the person who he said "shot up the place." He also posted a selfie of himself sitting in an airplane window seat. "The Bachelor" host Chris Harrison told Twitter followers his flight made it out before the airport was shut down. He also praised what he called an "incredible" reaction by first responders. "Glee" star Mark Salling was among those who didn't make it to LAX - because the shooting was at the terminal to which he was headed. He tweeted that he was canceling a weekend trip to Dallas as a result of the chaos.
