So there is a limit to a U.S. citizen's rights, and the Supreme Court just found it.
Please be advised that there is no right to bring foreign national spouses into the country, and no, the USG does not need to go into a lot of detail about it when they cite concerns about the criminality of said spouse.
The adjudication of Department of State v. Muñoz turned on the matter of tattoos, specifically, those tats on the Salvadoran husband of the respondent, an LA civil rights lawyer.
The tattoos actually sound pretty modest from the details given in the opinion, but still, our consular staff in Salvador must be experts on tat interpretation, and I will back their judgement as to the undesirability of admitting someone with those inkings into the USA.
On the occasion of the U.S Supreme Court's ruling on the legality of bump stocks, and also the occasion of Associate Justice Sotomayor's revelation that she fails to have any comprehension of what a bump stock is and does, I am posting the above clip from the 2018 movie Sicario: Day of the Soldato as a public service.
In this clip, Benicio Del Toro uses his left index finger to 'bump fire' a semi-automatic pistol and empty the magazine in a couple seconds.
No bump stock was necessary for him to do that, just some mechanical aptitude.
Sotomayor wrote in her dissent:
"All the textual evidence points to the same interpretation. A bump-stock equipped semi-automatic rifle is a machine gun because (1) with a single pull of the trigger, a shooter can (2) fire continuous shots without any human input beyond maintaining forward pressure."
"With a single pull of the trigger" is absolutely factually incorrect. If I recall the oral arguments correctly, the USG's own expert witness repeatedly tried to correct Sotomayor on her failure to grasp the fact that a separate trigger pull is needed to fire each and every round from a semi-auto.
The trigger has to first be pulled, then released to travel forward until it resets, then pulled again in order to fire more than one round. For each and every round. If you were to just pull the trigger back and hold it back, the weapon would fire no more than one round.
A 'bump stock' is a device that speeds up that cycle of pull-release-pull, and that is all it does.
Or, as Del Toro demonstrates, you can just hold your index finger steady and push the trigger against it, using the gun's recoil to bounce the trigger back and forth. Bang-bang-bang and you'll spray a lot of rounds out without good control of exactly where they're going.
A very poor practice, if you ask me, but it makes for a good movie stunt.
