I have this stupid notion that the "they" is the government and that "they" should have recognized this a long time ago. Hey FBI, if this is really a serious problem (I believe it is), then why weren't you out there backing someone like Trump when he was saying there were bad people coming over the border? Why aren't you screaming at the President and his cabinet about the problem? Why are they not doing anything about this problem that everyone and their grandma could see coming so much that they have been saying this exact thing since at least 9/11.
No, no, instead they come out and warn us about the thing "they" let occur that we have been warning them about for 2 decades. And my opinion, if a terrorist attack does go off in this country and it was found to have been someone who walked across the southern border, people who haven't been doing their damn job should be ruined.
