You mean good luck sneaking a bomber in across the southern border that is so closely guarded? Bringing in 2000 nuts to blow up DC would be no challenge at all with our border security. The challenge would be to keep the operation quiet enough that the feds don’t get wind of it beforehand.
Get wind of it? The FBI would offer them planning services, and then blame Trump.
They are most likely already here. Like so many mass shootings/shooters, I am sure they are on the government’s radar and might even be getting a little bit of assistance... If it can be blamed on the Proud Boys or related group, of course.
LOL.. They're too damn busy tracking parents of school students.
