Keep an eye out for what, Tilla? Take your average illegal, then stand an arab/isil/donkey humper next to him and there ain't no way in hell to tell the difference. They look alike, smell alike and speak a foreign language I don't understand. No, these guys know they have excellent cover and use it to it's maximum benefit.
I see em all the time. Walking down the highway. Illegal or Isil?
I still think the one's that will do us the most harm have been here for quite some time. Learning how to blend, dress, behave.
They know they can't take us (American citizens) toe to toe. So, they practice invisibility. Wait til the guard is down. And POOF!
Like being on guard for a ghost.
