There was a shooting at LA just weeks ago.

You mean Paul Anthony Ciancia who was pissed off about all the excessive security and deliberately targeted TSA agents hoping to commit suicide-by-cop?

Lots of less than spectacular events have occurred on soft targets over the past 10 years. Each of those may have easily converted in to a more spectacular attack.

Citing all attacks anywhere as justification for the TSA is a recipe for the unlimited ratcheting up of security. It is an enormous leap in logic to assume somebody with a semi-auto rifle or a crock-pot bomb is capable of getting them past pre-911 airport security and also doing something effective with it once they have. An attack on an airplane is simply too challenging for the vast majority of people to execute.
