ICE plans to spend millions more dollars on Tangles, and specifically Webloc. As we revealed, this is a tool that ICE can use to monitor entire neighborhoods. www.404media.co/inside-ices-...
escription: PenLink’s Tangles, supported by the Webloc database, provides ICE Criminal Analysts and law enforcement personnel a centralized capability to search, collect, analyze, and monitor publicly available open-source information from the open web and social media platforms. The service supports HSI criminal investigations by enabling users to develop leads and build subject, company, and commodity profiles using timely open-source data. It includes 100 credentialed user licenses for the Tangles Baseline and Webloc Bundle, access to searches and analyses, dark web sources, image and facial analysis tools, Weaver company sources, monitoring, online training, weekday support, 100 Co-Analyst licenses, one dedicated engineering support, and PenLink Academy training resources. The task order allows INTEL to procure licenses at discounted rates, with annual ordering up to $10 million. The total period of performance is September 25, 2026, through September 24, 2027.

ICE tried to conduct a dragnet search on REI customers in Minneapolis, apparently trying to ID a person who wore a particular beanie storage.courtlistener.com/recap/gov.us...

transaction information for all persons who had purchased a particular beanie, identified by item number, in the greater Minneapolis–St. Paul area from January 1, 2024, forward. Brisbois Decl., para. 3, Exhibit 3, Line 65. The summons requested the dates and locations of purchases, buyer identities and contact information, payment type, and complete credit-

We received 3 separate administrative subpoenas from DHS agencies seeking information for 11 Reddit accounts that posted content critical of ICE actions.

A First Amendment jawboning lawsuit in Illinois against the federal government can move forward. The suit claims the Attorney General illegally coerced Apple and Facebook to disable user content that tracked ICE activity.
Bondi and Noem “demanded, rather than requested, that Facebook and Apple censor Plaintiffs’ speech.” As such, the Court found that “Plaintiffs are likely to succeed on the merits of their claim that Defendants violated their First Amendment rights through coercion of Facebook and Apple.”

As reporting continues to surface about Madison Square Garden using facial recognition tech to identify, harass & ban people, it's important to highlight the many venues have prioritized artist & patron safety by pledging NOT to use this tech.
The image features a vibrant and colorful background that transitions through gradients of pink, orange, blue, and green. Overlaying this background is a series of bold, white text blocks against a black backdrop. The main message at the top states, "OVER 30 VENUES HAVE COMMITTED TO NOT USE INVASIVE SURVEILLANCE TECH." Below this, a numbered list includes three venue names: "1 BLACK CAT DC," "2 THE ROCKWELL," and "3 HOUSE OF YES." At the bottom of the image, another line of text reads, "HERE ARE JUST A FEW…" There are also decorative arrows pointing in various directions, enhancing the dynamic feel of the design.
