Guess what hero, the Constitution doesn't apply to foreign nationals on foreign soil, it just ain't in there. Are you advocating changing that?
Once an immigrant passes through the 3 mile limit, they are within the sovereign territory of the US. Given the immigrants of interest with visas in hand were turned away at their respective Ports of Entry (POE), their rights as persons under the sovereign control of the US and the Constitution were well and truly established AND violated.
The actions of the US authorities at the various POE's last weekend, by turning away people with authorized entry visas were violative of the Establishment, Due Process and Equal Protection Clauses of Amendments I & V. That makes the problems more than just an oversight, but rather egregious.
Further, in enforcing the EO before proper legal notice was given in the Federal Register as
required under 44 USC § 1507, the Trump & Co cabal violated, at a minimum, the Due Process Clause again bypassing the legal notice required by the statute. The EO wasn't even filed until Tuesday Jan 31 at 11:15 LONG AFTER it started to be enforced on Jan 28! Just go to the federal register Calendar to peruse the dates!
