Massive win for data privacy this morning

Today I wrote my first personal Substack post. I’m planning to visit POPOs -- San Francisco parks and plazas that anyone can go to, but which are accessible only through private property. I started with the park at Salesforce tower. 10/10: find out why open.substack.com/pub/granick/...

People say they want giant cars because they are "safer". Safer for whom? Weigh the fractional benefits to the passengers with the devastating consequences to pedestrians and bikes. No one wants to die OR kill someone else in an accident. Think about both before you buy.

The Michigan Law Review's annual book review issue is out, which includes @mtokson.bsky.social's review of my book, "The Digital Fourth Amendment." The review is called "Fourth Amendment Anti-Theory," and it is available here, w/ the 1st 4 pages below. repository.law.umich.edu/cgi/viewcont...

I guest-hosted @masnick.com’s podcast Ctrl-Alt-Speech. Doing anything with Mike is fun -- his expertise is unequalled. Here we talk about Internet bottlenecks and how even our vast internet can be regulated and censored if you pressure the right players. podcast.ctrlaltspeech.com/2315966/epis...

New Ctrl-Alt-Speech with guest host @granick.bsky.social: Message in a Bottleneck. This week, we talk about the various bottlenecks and chokepoints on the internet: payment processors, app stores... some gov't regulators. podcast.ctrlaltspeech.com/2315966/epis...

Just got back from my nephew's graduation. In a diverse class of 1000, everyone's name was pronounced correctly, thanks to AI. BlueSky's gleeful celebration of failures should be measured against the backdrop of unheralded successes and a long tradition of mangling unfamiliar names.

ICE use of Palantir systems now means agency officials effectively have a list of 20 million people readily accessible on their iPhones, increasing the speed at which ICE can find houses to raid and people to arrest. www.404media.co/ice-agents-h...

These secret government investigations fly in the face of the Constitution www.washingtonpost.com/opinions/202...

I'm honored that Dark Reading has included me as one of the top 20 impactful people in Internet security. The company I'm keeping on that list is humbling. When I started in this field, I think I was the first lawyer entirely committed to protecting hackers from legal threats.

Brooke Jenkins's SF DA's office won't file conspiracy or accomplice charges against police officers who participated in and/or covered up a sexual assault, but anti-genocide protestors on the bridge face conspiracy charges carrying potentially 14 years in prison. We said this would happen.

San Francisco DA Brooke Jenkins takes a law enforcement hatchet to demonstrators' rights in the streets and in the courtroom:

My Facebook feed is now entirely Chonkers. The algorithm Knows me.

Here's a long article after a long hearing after eight years of advocacy.

I read all the amicus briefs in United States v. Chatrie, the Supreme Court geofence case, so you don’t have to. An expert agrees this is the best one: open.substack.com/pub/granick/...

ACLU's @granick.bsky.social was once called "the NBA all-star of surveillance law" by @wyden.senate.gov. And now, after many years, she's hanging up her jersey. Read about her important fight over the past decade to protect our data from overbroad digital warrants. www.aclu.org/news/privacy...

Most convincing part of the New York Times piece on Satoshi: "Like Satoshi, Mr. Back used two spaces between sentences, an outdated practice that suggests Satoshi is older than 50. Mr. Back is 55." Indeed. Who even does that anymore?

From 2006 to 2012, I had a blog called The Shout: Opinions on Everything. Fourteen years later, The Shout is back! Same emphatic opinions, but now it's a Substack. Subscribe for my posts (free), or just tune in for awhile.

The Trump administration is pursuing a future where police and corporations control who gets to fly drones in our skies. A new report from our privacy expert Jay Stanley breaks down this disturbing trend and what lawmakers must do to protect the public and press's right to use drones.

NEW: Apple provided the FBI with the real iCloud email address hidden behind Apple’s ‘Hide My Email’ feature, which lets paying iCloud+ users generate anonymous email addresses, according to a recently filed court record.

It has been years since I have been as excited about something as I am about this.

Seventeen years of worrying...

Let's not call a second strike to kill survivors a "double tap".

I was on a fascinating panel put on by Helen Maria Nugent at CCA about AI and Art: Contemplating an Algorithmic Future, as part of CCA's After Intelligence event. My presentation, on AI and surveillance, is available here after-intelligence.cca.edu/events/day-1...

Unlike, say, data analytics giant Palantir, Ring is a surveillance network that homeowners have by and large deployed themselves, powered by fear mongering against our neighbors and unfettered consumerism. www.404media.co/with-ring-am...

www.nytimes.com/2026/02/13/t... In recent months, Google, Reddit, Discord and Meta, which owns Facebook and Instagram, have received hundreds of administrative subpoenas from DHS. This explosion is because they want to punish people for resisting their violent, discriminatory deportation campaign.

CIS Affiliate @granick.bsky.social reviews Orin Kerr's "The Digital Fourth Amendment," agreeing with his "equilibrium-adjustment" theory but criticizing his cautious approach to tech surveillance & his 1920s baseline that ignores racism in policing harvardlawreview.org/print/vol-13...

I'm delighted that the Harvard Law Review has published a book review of "The Digital Fourth Amendment." The review, by @granick.bsky.social, is here. harvardlawreview.org/print/vol-13...

@orinkerr.bsky.social wrote an excellent book, The Digital Fourth Amendment, and I wrote a review of it. harvardlawreview.org/wp-content/u... Here's where you can buy the book: a.co/d/04G3OPoz

DHS is waging a bi-coastal assault on the free speech rights of people speaking truth about power. Last fall, in a separate case, the agency unsuccessfully sought the identity of our client who discusses ICE activity on Instagram. www.aclunorcal.org/press-releas...

Bay Area friends: I'll be speaking at this California College of the Arts event tomorrow, talking about the use of AI in the criminal system. There'll be other cool speakers too. RSVP! It's free... after-intelligence.cca.edu

ICE tear gassed a bunch of children on Saturday. This was a massive escalation of force. They were shooting tear gas at the back of the crowd, it took these unmasked people maybe 3-5 minutes in the cloud of tear gas to escape in without trampling. www.theverge.com/policy/87278...

Homeland Security is targeting Americans who criticize it with unfounded investigations fueled by judicially-unsupervised administrative subpoenas. This article tells the story of our client who was so targeted. www.washingtonpost.com/investigatio...

If a foreign country bombed us (killing noone-is-reporting-how-many Americans) and loaded Trump onto an airplane for a foreign prison, would we call it "regime change" or an invasion? Would we say Trump was "captured", or abducted? News needs to use the right words, not euphemisms.

I gave money to San Francisco Aid for Animals, a nonprofit that helps pay for medical care for animals whose families cannot afford the treatment. There are few greater joys in life than the love between a pet and an owner, and money shouldn't be allowed to come between them. www.sfafa.org
