I find this situation hilarious. Thankfully no one was hurt by a trigger happy SWAT rookie.
But, this just proves that the TSA would have preventing nothing if this was a real situation. With all the invasive pat downs and body screenings they still deem it necessary to keep SWAT ready on the runway. And the reality is they have to keep that kind of security because the TSA is worthless. The DHS (department of homeland security) has no idea how to prevent any attack on the USA, and can only be ready for when one happens. But that is part of the plan, they want to justify their existence and a bigger budget.
