Kourtney Kardashian touched down in L.A. and was greeted by a tighter security detail than usual, and they immediately went to work ... shielding her from a horde of media.
Kourtney was whisked through LAX with 2 huge guys surrounding her -- while other bodyguards cleared a path to her waiting SUV.
As we reported ... Kim's trusted bodyguard, Pascal Duvier, was not with her at the time of the armed robbery -- instead he was with Kourt and Kendall Jenner in a Paris nightclub.
Much like Kim and Kris Jenner Monday morning in NYC -- it's clear the whole family is going to be rolling deep with bodyguards.
