Thank you for the link/clue, PK.
When I put it in "search" it came up with results that reminded me of old law enforcement techniques used to nab a "bad guy" - watch all of his/her known contacts/habitual connections.
This "old" technique would almost certainly ID activity in/around known hotbeds. Including "camps" where high intensity training is under way as well as popular and commonly accessed family or social nodes. Border crossers will NOT operate without contact and support from like minds, birds-of-a-feather, already here... (my bet).
Of course, our weaponized and mega-funded security apparatuses here in the US are steps ahead of anything you or I might dream up. They know things. Which means... a Hamas-like terror operation on American soil, allowed to go forward, will be, by definition, a "false flag" event.
Our win?
The "blowback".
Of which there always seems to be some.
