How Information Actually Moves…and Why That’s the Part That Matters

The Jack Hopkins Now Newsletter #763: Wednesday, February 4th, 2026.

In the previous article on the use of data collection tools by our federal agencies, I showed you the outline of the machine.

What tools exist.
What categories of data are involved.
Why the idea that this stays “neatly targeted” doesn’t survive contact with reality.

This article goes where the free one couldn’t responsibly go.

Inside the flow.

Not theory. Not vibes. Not panic.

Mechanics.

Because once you understand how data actually moves…how it’s collected…normalized… routed…retained…and recombined…you stop arguing about intent and start seeing leverage.

And…leverage…is the only thing that matters in systems like this.

Start Here: Enforcement No Longer Begins With a Person

This is the conceptual shift most people miss.

Modern enforcement systems do not begin with a human target.

They begin with data ingestion.

A record enters the system.
A signal is logged.
A relationship is inferred.
A pattern is surfaced.

Only later…does a human get involved…and often only to approve…prioritize…or act on what the system has already suggested.

That inversion changes everything.

In the old model:

Person → suspicion → investigation → data

In the modern model:

Data → correlation → prioritization → person

ICE did not invent this model.
But…it is now operating inside it.

Step One: Collection Is Distributed by Design

ICE does not “collect data” in one place.

It pulls data from many places…some directly…some indirectly…some episodically… some continuously.

That includes:

• Internal DHS systems

• Partner agencies (federal, state, local)

• Commercial vendors

• Legacy databases built for other purposes

• Data originally collected for non-enforcement reasons

The critical point is this:

Most of this data was not collected with ICE as the end user in mind.

It was collected for:

• Licensing

• Travel

• Employment

• Benefits

• Security screening

• Marketing

• Administration

ICE’s advantage is not collection alone.

It’s access plus integration.

Step Two: Normalization-Turning Messy Records Into “Usable Truth”

Raw data is garbage.

Different formats.
Different standards.
Different error rates.
Different assumptions.

Before any “analysis” happens…data has to be normalized.

That means:

• Names standardized

• Addresses reconciled

• Dates aligned

• Identifiers matched or probabilistically linked

This is where vendors matter enormously.

Because normalization is not neutral.

Decisions are made about:

• What counts as a match

• How confident a match must be

• How conflicting records are resolved

• Which source “wins”

These decisions are often:

• Proprietary

• Undocumented publicly

• Invisible to the people being evaluated

Once normalized, the data feels authoritative…even when it’s built on soft assumptions.

That’s a dangerous illusion.

Step Three: Identity Resolution-When “Maybe” Becomes “This Person”

Identity resolution is the hinge point.

This is where:

• Multiple records are linked to a single profile

• Uncertainty is compressed into confidence

• Adjacency becomes association

You don’t need to be the subject.

You only need to be:

• Connected

• Proximal

• Overlapping

Same address.
Same device.
Same vehicle.
Same contact network.

From the system’s perspective…these are not “context.”

They are signals.

And signals accumulate.

Step Four: Analytics-The Quiet Ranking of Human Attention

Here’s the part that makes people uncomfortable when they really understand it.

Modern systems don’t just store data.

They rank.

Not morally.
Operationally.

Who surfaces first.
Which leads look “productive.”
What gets attention today.
What gets deferred indefinitely.

Analytics platforms:

• Score

• Prioritize

• Cluster

• Flag

Not because someone is evil…but because humans can’t handle volume.

So the system decides what’s “worth looking at.”

And over time, people trust the system’s judgment more than their own…because it’s faster…cleaner…and feels objective.

This is how discretion quietly migrates from humans…to software.

Step Five: Routing-Who Gets to See What (and Who Doesn’t)

Once a profile exists, it doesn’t live in one place.

It moves.

Routed to:

• Investigators

• Field agents

• Analysts

• Partner agencies

• Task forces

Each with different permissions.
Different interfaces.
Different retention rules.

Here’s what matters:

Routing decisions determine accountability.

If data moves across organizational boundaries:

• Oversight fragments

• Responsibility diffuses

• Errors propagate

And when something goes wrong…no single actor owns the outcome.

Everyone followed the system.

Step Six: Retention-The Data Doesn’t Leave When You Do

One of the most persistent myths is that data “goes away.”

In practice:

• Records linger

• Backups persist

• Derivative data remains

• Logs outlive the original context

Even if:

• A case is closed

• A lead goes nowhere

• A person is cleared

The profile often remains.

Dormant…but intact.

And dormant data…is not harmless.

It becomes raw material…for the next integration.

Step Seven: Feedback Loops-When Systems Learn What “Works”

This is subtle…and critical.

Systems learn from outcomes.

If a certain pattern leads to an arrest…a detention…or an administrative success…that pattern becomes validated.

Not ethically.
Operationally.

The system doesn’t ask:

Was this fair?

It asks:

Did this produce an actionable result?

Over time:

• Certain profiles surface more often

• Certain neighborhoods light up more frequently

• Certain associations look “riskier”

This is how bias becomes structural without anyone choosing it.

Step Eight: Why “Efficiency” Is the Most Dangerous Word in the Room

Every expansion of this system is justified the same way:

Efficiency.
Modernization.
Resource constraints.
Public safety.

Efficiency sounds neutral.

But efficiency…always has a direction.

It favors:

• Speed over deliberation

• Automation over discretion

• Scale over nuance

And once efficiency is achieved…rolling it back feels irresponsible.

That’s the trap.

The Tools: What They Can Collect, and How They Do It

If you want to understand this system like an adult…you have to stop thinking “ICE” and start thinking stack: platforms that query…platforms that aggregate…platforms that extract…and platforms that link.

1) Palantir ICM / FALCON: the “case brain” that pulls from everywhere

Palantir’s Investigative Case Management (ICM) and related ICE systems are best understood as the hub…a case platform designed to import…aggregate…search…analyze…and visualize data from many sources.

What it can pull together (in practice):

• Identifiers and biographical details (names, aliases, DOBs)

• Address histories and contact points

• Agency-held records (immigration, enforcement, investigative)

• Link analysis (“who is connected to whom”)

• Tips/leads and case notes, plus automated summaries and triage (in newer AI tip-processing add-ons)

How it does it:

EPIC’s documentation describes ICM as more than a UI: it includes an Interface Hub that manages the movement of information between ICM and external repositories, and an HSI Data Warehouse that stores case information for sharing/reporting.

That matters because “querying” isn’t just a search…it’s routing and persistence inside a case environment.

2) The telecom layer: Palantir + PenLink (telecommunications evidence + timelines)

EPIC describes ICE’s ICM environment as including a telecommunications storage capability (TLS) and an interface with PenLink…designed to store case-related telecommunications information obtained via subpoena or similar legal process.

PenLink markets a platform that can unify call detail records…location data…and digital evidence into a consolidated investigative timeline…and also advertises “live” collection capabilities in lawful interception contexts.

(Important: the how here is usually legal process + carrier data + agency workflows…this isn’t “satellite magic,” it’s record ingestion and correlation.)

3) Commercial “dossier” tools: Thomson Reuters CLEAR and LexisNexis Accurint

These tools are not “ICE databases” in the public imagination. They’re commercial investigative platforms that compile and connect huge volumes of public + proprietary records.

CLEAR (Thomson Reuters) markets itself as an investigative platform providing access to a “vast collection of public and proprietary records” and analytics to connect people…businesses, assets…and affiliations.

A major criticism of these systems is not that they invent data…but that they collapse many sources into one easy interface…which changes the speed and scale of investigations.

Accurint (LexisNexis) explicitly markets rapid access to identity records that can surface addresses…phones…relatives…associates…and assets…compiled from “thousands of sources.”

How they do it:

Not by “breaking into” your accounts. By buying…licensing…and aggregating records from a wide ecosystem…public records…proprietary feeds…and commercial data sources…then using linking/identity resolution to present a coherent profile to investigators.

4) Warrantless-ish location data channels: Venntel + Babel Street (DHS buying broker data)

One of the clearest documented pathways for “modern surveillance” is the purchase of commercial mobile location data by DHS components via data brokers like Venntel and Babel Street.

What this can include:

• Latitude/longitude pings tied to a mobile advertising identifier

• Timestamped movement trails

• “Pattern of life” inferences (home/work/regular routes)

How it does it:'

Typically through the ad-tech ecosystem: apps collect location (often via SDKs), data is sold onward, and brokers package it for government clients. The ACLU’s released records describe DHS purchases of “vast quantities” of such data.

This is why people say the line between “marketing” and “enforcement” is often access.

5) Phone extraction / device forensics: GrayKey (Magnet Forensics)

ICE’s Homeland Security Investigations (HSI) has reportedly contracted for GrayKey licensing…a well-known mobile forensic access tool used by law enforcement.

Magnet Forensics markets GrayKey as a tool that can “lawfully access and extract encrypted or inaccessible data” from mobile devices.

DHS’s own testing documentation discusses GrayKey’s ability to acquire active data from internal memory on supported devices…with results varying by extraction technique.

What “device extraction” can yield (depending on device state, OS, and legal authority):

• Contacts, call logs, SMS/iMessage-style content

• Photos, videos, files, notes

• Location history artifacts

• App data artifacts (which can include messages and metadata, depending on app and encryption)

• Deleted remnants sometimes (varies heavily)

How it does it:

Not “remote mind-reading.” It’s typically physical access + forensic acquisition workflows: the device is connected…data is extracted under tool-supported methods… then parsed into reports/timelines in forensic suites.

6) The hidden superpower: linking across all of it

None of the above is the whole story by itself.

The real power comes from the linking layer:

• A phone number from a device extraction can be cross-walked to subscriber/associate records (Accurint)

• A plate hit or address can become a “node” inside a case graph (ICM/FALCON style systems)

• A location trail can become corroboration…prioritization…or “confidence” when paired with other signals (broker data)

That’s why this isn’t “one tool.”

It’s an architecture where each new dataset raises the value of every other dataset.

And…that’s also why the public keeps missing the point: the danger is not a single scary capability. The danger is the compound effect of speed…integration…and persistence.

What Changes When Politics Change

Here’s the part people avoid saying out loud.

These systems are agnostic to political intent.

They don’t care who’s in charge.

Which means:

• Priorities can be re-weighted

• Thresholds can be adjusted

• Sharing rules can be loosened

• Targets can be broadened

Without rebuilding anything.

Infrastructure built for one moment…persists into the next.

That’s why orientation matters more than outrage.

What This Article Is Not Saying

Let’s be clear.

This is not:

• “ICE is omniscient”

• “Everyone is being watched equally”

• “There is no legal process”

Those claims are sloppy.

This is saying:

• The machinery exists

• The incentives are clear

• The guardrails are thinner than people assume

• And dependency has already set in

Once dependency sets in…reform becomes exponentially harder.

The Only Questions Worth Asking Now

Not:

Is this legal?

But:

• What are the limits?

• Who enforces them?

• How are errors corrected?

• What data never expires?

• What happens under stress?

• What changes quietly over time?

Those are adult questions.
