Whoops! That was meant to be a 4. But yeah, like a 7th grade civics class (in the US) would’ve educated you on the role of case law as it relates to interpreting the Constitution. Presumably your home country didn’t spend much time on it though, which makes sense!
But the 4th amendment doesn't appear to provide 'the people' protection to non-immigrants. A US citizen cannot be compelled to produce their citizenship with out a warrant, whereas a non-immigrant can be compelled to produce their papers on the spot.
Also the recent Bruen ruling was taken by at least one case law in Illinois [] that applied 'the people' the same as the other amendments (as it was in early American history), when they overturned (from memory) a prohibited possessor conviction. They just came to a different conclusion what 'the people' is and held an illegal immigrant (as applied) was part of 'the people'.
And finally, despite the fact the case law isn't as 'unequivocal' as you seem to think, you still have to get around the fact that the very writers of those amendments believed the rights in the bill of rights were god given natural rights, thus case law can at best reflect them and at worst incorrectly apply them but not modify the natural right. In fact this was part of the reason why the 2nd amendment was written, was because the founders needed a check when the case law, legislator, and executive all applied the constitution in contradiction to the acknowledged natural rights.
Are you American/did you attend American middle or high schools?
