United States: French researcher turned back for expressing “personal opinion on Trump administration’s policy

Etats-Unis : un chercheur français refoulé pour avoir exprimé « une opinion personnelle sur la politique menée par l’administration Trump »

"The space researcher was allegedly randomly checked on arrival, during which his professional computer and personal telephone were allegedly searched. Similarly, messages about the Trump administration’s treatment of scientists have been found."
1st Amendment protections on freedom of speech apply to everyone in the USA, regardless of citizenship. Frenchman should sue.
That doesn’t de jure apply to non-citizens at the border, never mind de facto.
Rights don't apply to non-citizens? You sure?
Visitors to the US have been asked if they were members of the communist party since forever though?
IDK if those who replied "yes" would be sent back, but I do remember reading about Chinese communist party members being denied entry to the US.
I don't see much difference between this and that as far as the 1st amendment is concerned... aren't you idealizing the 1st amendment (and/or how seriously the US takes it)?
PS: let me make clear that I'm not trying to defend the indefensible behaviour of the Trump administration in any way
There’s no first or fourth amendment rights within 100 miles of the border of the USA. Probably other missing rights too.
That's not true, because the Constitution applies to the whole place. Americans and non-citizens freely exercise those rights in those areas daily.
If any agent of the government tells you otherwise, you must educate them and enforce the free exercise of your own rights.
The important judges are trumps pals.
I was under the understanding that when in customs TSA overrides an American Citizens constitutional rights...
Basically, you don't have a 1st ammendment right as an American Citizen.
Nope, that is not correct. The rights remain in place and may be exercised at will.
