Musician and comedian Paul Harris was an eyewitness to the attack that killed a TSA worker.

He says says experiencing this tragedy has forever changed his life and awareness about personal safety.

After performing in California Harris was finally headed home when the unimaginable happened.

"I made it all the way through the screening area and had taken my shoes off and put everything in the tray and that's when the first shots rang out. We immediately hit the floor and tried to hide," Harris explained.

He adds the only thoughts going through his mind at the time, were survival strategies.

"Stay alive. That's it. Just to run for your life."

Amid all the chaos, Harris and other passengers glanced up in horror as 23-year-old Paul Ciancia continued to fire off rounds.

"I saw the shooter coming up the terminal and we scrambled and ran on the tarmac," said Harris.

He was detained for questioning for several days before being allowed to re-claim his baggage and fly back to Branson.

"The next day, getting on an airplane was pretty tough but I had to get back on that horse and I will continue to ride.," said Harris. "If you stop doing your everyday thing then they win," he explained.

This tragedy has brought airport security to the forefront of debate and has raised difficult questions about arming TSA agents. Harris credits the agents at L-A-X and their airport security measures with saving lives:

"LAX was prepared. There's been question about how they let that happen and their actions. I though their actions were spot on. They took that guy out in 3 minutes from the time he started until the time it was over.

Harris looks at TSA workers, LAX employees and the LAPD as guardian angels whose security measures prevented the outcome from becoming much worse.

"He had 100 rounds of ammunition it didn't go down like he expected it to. He had 100 rounds and I don't know how many he got off but he was expecting to do a lot more devastation than he did."

Harris says one thing that stood out to him in all of the chaos is the human compassion of others who went through the attack. When he was in the terminal without shoes or a cell phone to call his wife strangers volunteered to help. He says these acts of kindness "restored his faith in humanity".
