INTERESTING CASE: Police can detain a person on the scene when they execute a warrant. But can they call up a suspect and make up a fake story about needing him to be home to get him to be there so he can be detained? CA9 rules 2-1 that they cannot.

I'm not sure what I think of this. It's true that a ruse can expand what the government can search and seize, manipulating the rule. OTOH, don't Ky v. King and Navarette v. CA suggest that police steps that manipulate rules are okay as long as they don't themselves violate 4A?
The majority opinion is weirdly free form in some ways, in that it conducts a balancing test over the ruse: It concludes that the decision to do the ruse fails the balancing test. But the 4th Amendment balancing test is only for searches and seizures, and a ruse is neither.
Anyway, interesting case.

Oh, and if you have views of it, arguments based on actual 4th Amendment law are particularly welcome. :)

NOTABLE: Google announces dramatic changes to its "location history" function that should nullify all geofence warrants going forward—and I wouldn't be surprised if that is the point. Code is law, as they say.

As I read this, Google will no longer keep geolocation data even for the subset of users that turn on location history. The data will only be stored locally. Geofence warrants are used when the govt has no suspects, to get some leads, so this will likely defeat the technique.
There's a very important surveillance story to be written on how Google came to this decision. I hope we'll get to read it, I'd be very interested to know.

I'm reading the newly-released transcript of Twitter's proceedings before Judge Howell on Twitter's compliance with the warrant for Trump's account. Here are thoughts as I go.
dcd.uscourts.gov/sites/dcd/file…
First, this should be good. The lawyers are experienced lawyers from WilmerHale, and Judge Howell knows more about the Stored Communications Act than any other district judge. This is no one's first rodeo.
p. 6, Howell is starting off frustrated with Twitter. Image

“A lot of times he’ll tell me that he lost, but he wants to keep fighting it, and he thinks that there might be enough to overturn the election." -- Mark Meadows on Trump, November 18, 2022, according Cassidy Hutchinson.
One interesting thing about the latest Trump indictment is that it doesn't detail reports that Trump admitted he lost, leading some to suggest that they have no such evidence. But it not being detailed doesn't mean it doesn't exist. cnn.com/2023/06/06/pol…

Is access to Automated License Plate Reader info a 4th Amendment Search? Oral argument on this in US v. Mapson, 21-13668, see here, 2nd link.

A few thoughts on the argument.

ca11.uscourts.gov/oral-argument-…
Defendant's side, 1st 25 minutes, didn't have much 4A discussion. There are three co-defendants, and only the 2nd defendant is making the ALPR argument. And it's being made in a very tentative way.
At the argument, the defense counsel arguing the ALPR point conceded that a single ALPR reading would not be a search. When asked where the line was, he just said it should be a totality test. (Aside: This is what you say when you don't know; no one knows.)

Yesterday, at the 8th Circuit judicial conference, Justice Kavanaugh gave a talk that included two interesting pieces of advice for Supreme Court advocates—one explicit, the other implicit. Tne talk isn't online, so I thought I would tweet about them. #appellatetwitter

🧵
First, he said that several Justices, himself included, believe that the two-minute uninterrupted opening time they now give advocates is a really critical time for advocates. You should use it well.
He suggested that Justices listen carefully to that opening, in part because they're listening for subtle ways that the argument may have changed between the written brief and the argument. They know arguments are mooted, and some ground may have shifted.
