Shooting at The Los Angeles International Airport

I found an article that might be interesting and saddening from the New York Times. There On November 1 there was a shooting at The Los Angeles International Airport. Unfortunately, one emergency responder was shot and killed during this incident. From what I have been gathering; it seems like there is a communication breakdown with TSA and other emergency responders. The Los Angeles International Airport will strengthen their security due to this tragedy. Emergency responders from now on will be escorted by police officers with bulletproof vests. In addition, there is more communication breakdown during the five-hour lock down of the airport. People with mobility issues were not given the help that they needed and people with medication could not access their medication because it was inside the locked down. The Los Angeles International Airport home I'll strengthen their security and provide additional training to other staff to prevent these miscommunications from happening.

I don't know how this could happen with the security measures that are in place now days. I recently went to Florida and security was very tight and handled delicately. With my mobility issues I had to be patted  down and swabbed for any type of residue. I understand that is for my own good to have these types of security measures, so I'm appreciative of what they do. At the same time I just don't know how the Los Angeles International Airport security staff could let this happen! How can a shooting occur with these types of security measures in place? Here's the link to the article:

please let me know what your opinion is! I'm still puzzled at how anything like this could happen!
