Isn’t this against the US constitution? Razor wire along the state border and checkpoints on roads that cross the state border are kind of nuts. I read a comment joking that the wire and road checkpoints were to keep Texan women from escaping to New Mexico, which got a bitter laugh out of me.
not explicitly. the Constitution’s Privileges and Immunities clause is written assuming freedom of interstate travel, but the Framers thought the right to travel was so fundamental and obvious it did not need explicit enumeration. the right to travel was enumerated in article 4 of the Articles of Confederation however and the Supreme Court has upheld it several times on that basis
