It's how the US government (no longer really by the people) doing what it pleases.
Like a dictatorship & not the republic it was designed to be.
Funny how the Constitution gets applied when convenient & ignored when it's not.
The unpatriot act lets Homeland Security get by with almost anything.
If citizens get together to plan to stop this it becomes a conspiracy they can be imprisoned for. Instead of the revolution the Constitution is supposed to allow if the government gets out of control by "We the People".
HS uses the "not through customs" loop hole to bypass the Constitution in a situation like this one . Saying the Constitution doesn't apply because the person even a US citizen is outside the border.
I bet if a cruise ship at a port outside the border discriminated against one race we would see the Constitution applied "outside the border".
So the US government is full of hypocrites .
I think the only cure at this point is a "New American Revolution" .
If that doesn't happen "We the People" will continue to be under the boots of the government.
