No—see McGuire, Silverman, Jardines, etc.

In any event, if you're wondering why others aren't looking at it the way you think they should, I think my replies at least suggest the framework others have that explains why they're not.

I haven't seen a formal denial that the dog is capable of that; it was an issue in the Supreme Court's oral argument in Florida v. Harris a while back, if I recall correctly.

orinkerr.bsky.social
But the Supreme Court has rejected for at least a century your apparent premise that common law doctrines from property law apply to 4th Amendment law, so ignoring that and expanding that premise to tort law seems something you’d need to justify.

orinkerr.bsky.social
Why do you think principles of tort law are part of the Fourth Amendment? They're different bodies of law that do different things, so I'm not sure why you think one applies to the other.

Does a Fourth Amendment search occur when a drug detection dog jumps unprompted into a suspect's car and then alerts? Here's why I think the answer is "yes." new from me at Volokh, a deep dive for the law nerds.

Unfortunately, the Supreme Court may grant your wish and reconcile them in the next few years.

Tenn SCT: Although a statement obtained in violation of Miranda was not admissible at trial, it could be still used to help generate probable cause to search under the Fourth Amendment. tncourts.gov/sites/defaul...

CT SCT: No 4A search occurs when police get trash collectors to bring suspect's trash to cops, find a belt in the trash and get DNA from it to ID suspect.

Two Justices: this should be a search under the state Constitution. www.jud.ct.gov/external/sup...

Immigration Arrests in the Interior of the United States: A Primer

I'm confused. You're the one saying that the article supports your view. I read the article in response and pointed out to you that it doesn't support your view. If your reply is that the article isn't worth following because SCOTUS has rejected it, then I wonder why you suggested it at all.

This Indiana Supreme Court case is a reminder that curtilage is not just a concept in Fourth Amendment law—here, it's used in a state constitutional provision on property taxes.

When it refers to "physical seizures," it has in mind direct physical seizures of land— that is, physically taking over someone's land. As I read it, the article argues that this is the only thing the drafters had in mind. True or not, I'm not sure how that helps here.

orinkerr.bsky.social
Thanks. Seems worth noting that this article argues for a very narrow interpretation of the takings clause and does not mention search and seizure or warrants at all.

orinkerr.bsky.social
What history about the scope of Takings Clause liability are you relying on when you call this ahistorical?

CA7: Under circuit precedent, homeowner can't sue under the Takings Clause for damage to house caused by execution of a search warrant there.

Tragic news from Canada where the Canadian Supreme Court has gone from the official dress on the left to the one on the right
Canadian Supreme court. Everyone is dressed in bright red wooly gowns, with a beige trim. It looks sort of like a Santa robe The Canadian Supreme court. Everyone is dressed in black gowns with a bright white kravat, and two thin red vertical lines on the side of the robe

Judge: That's what I'll do. Prohibit federalization or deployment of any NG troops into Oregon. For all reasons in prior opinion. Deployment of federalized military is ultra vires and contrary to law, violating Title 10, section 12406. I also find it's likely that defendants violate 10th Amendment.

Florida court: We think the enactment of medical marijuana at the state level, and perhaps legalization of hemp at the federal level, means the smell of cannabis no longer generates probable cause, and we certify the question to the state supreme court.

NEW: Judge Crenshaw finds that the Trump admin's criminal prosecution of Kilmar Abrego Garcia may well be vindictive—and greenlights discovery and an evidentiary hearing. storage.courtlistener.com/recap/gov.us...
MEMORANDUM OPINION
By way of context, a federal prosecutor is the representative not of an ordinary party to a controversy, but of a sovereignty whose obligation to govern impartially is as compelling as its obligation to govern at all. The obligation to govern impartially concerns, above all, the state's exercise of coercive power-meaning its power to deprive its subjects of life, liberty, or property... As a representative of the state, a prosecutor's exercise of coercive power must be impartial ... [in] that prosecutorial power may not be exercised vindictivelymeaning that the prosecutor may not punish a defendant for exercising a protected statutory or constitutional right.
United States v. Zakhari, 85 F.4th 367, 384-85 (6th Cir. 2023) (Kethledge, J., concurring) (citations and quotations omitted). This context frames review of Defendant Kilmar Armando Abrego Garcia's ("Abrego") motion to dismiss his indictment for vindictive and selective
prosecution. (Doc. Nos. 104-05). The Government opposes the motion (Doc. No. 121), and Abrego has replied (Doc. No. 127). Abrego's motion is not ripe for decision because he seeks discovery and an evidentiary hearing because there is some evidence of vindictiveness here. For the reasons that follow, the Court holds that the totality of events creates a sufficient evidentiary basis to conclude that there is a "realistic likelihood of vindictiveness" that entitles Abrego to discovery and requires an evidentiary hearing before the Court decides his motion. United States
v. Andrews, 633 F.2d 449, 457 (6th Cir. 1980) (en banc), cert. denied, 450 U.S. 927 (1981).

I think this was a successful paper academically, but it's a bit disappointing that, given its obvious doctrinal importance, it has been cited in a published judicial opinion only once.

This was published 10 years ago, and I believe it's still the leading article on the topic.
