The Trump administration’s unprecedented diversion of federal law enforcement to immigration has gutted gun crime prosecution across the country. Eighty percent of ATF special agents have been reassigned to immigration cases as part of a surge of 23,000 federal officers redirected to deportation efforts, and the results are showing up in courtrooms nationwide: gun prosecutions dropped more than 10% in 40 of 94 federal court districts in 2025, including areas around New Orleans and Milwaukee — cities with some of the highest murder rates in the nation. The tradeoff is stark.
In Maryland alone, federal prosecutors charged only 89 people under top gun statutes, down from 131 the prior year — a 32% decline and the lowest figure in at least 25 years. Meanwhile, the federal courts themselves are buckling under the weight of more than 18,000 habeas corpus petitions filed by detained immigrants, a volume that exceeds the total filed under the last three administrations combined. This article breaks down how the immigration enforcement surge drained ATF and other agencies, what it means for gun violence enforcement, how courts are struggling to keep up, and what the broader consequences look like for federal law enforcement priorities.

Why Are Federal Gun Cases Being Dropped as Prosecutors Focus on Immigration?
The core problem is resource allocation. When the trump administration directed 23,000 federal officers toward immigration enforcement, agencies that handle firearms, drugs, and other federal crimes lost the personnel needed to investigate and prosecute those cases. Nearly 1,200 ATF agents — roughly half the agency’s workforce — spent at least some time on immigration duties instead of gun enforcement during 2025. After a May 2025 DOJ directive formally reassigning agents, gun enforcement actions dropped 14.2% in June alone. This is not a temporary shuffle. Between January and October 2025, 219 ATF criminal investigators left the agency entirely, representing nearly 40% more departures than the previous four years.
The proposed ATF budget would cut 550 of 600 remaining firearms license investigators, which would leave a skeleton crew to oversee the country’s tens of thousands of gun dealers. Under these conditions, ATF did not revoke a single dealer’s license in the first four and a half months of 2025, putting the agency on pace for a 90% drop from Biden-era enforcement levels. The contrast is worth understanding clearly. Under the prior administration, ATF was ramping up enforcement against rogue gun dealers and straw purchasers as part of a broader strategy to reduce illegal firearms trafficking. That work has effectively stopped. The agents who built those cases are now processing immigration detainees or assisting Border Patrol operations.

How Many Federal Agencies Have Been Diverted to Immigration Enforcement?
ATF is far from the only agency hollowed out. Approximately 23% of FBI agents have been detailed to immigration work. Around 75% of DEA agents have been redirected. About a third of U.S. deputy marshals are now working immigration cases. Nearly all Homeland security Investigations agents — whose original mandate includes investigating transnational crime, cyberattacks, and human trafficking networks — have been diverted to immigration duties.
The consequences extend well beyond gun cases. Federal drug prosecutions have fallen to their lowest level in decades, even as the administration publicly emphasizes the fentanyl crisis as a national security threat. This creates an odd contradiction: the same administration that has framed immigration enforcement as essential for stopping drug trafficking has simultaneously pulled the agents and prosecutors who actually build drug trafficking cases off those assignments. However, if you are someone who believes immigration enforcement should be the top federal priority, this tradeoff might seem acceptable. The issue is that it was never presented as a tradeoff to the public. Administration officials have continued to claim they are tough on crime across the board, without acknowledging that gun and drug enforcement has been severely curtailed to make the immigration surge possible. The data tells a different story than the talking points.
Federal Courts Overwhelmed by Immigration Habeas Petitions
The immigration enforcement surge has not only drained investigators and prosecutors — it has swamped the courts themselves. More than 18,000 habeas corpus petitions have been filed by detained immigrants, a number that exceeds the combined total filed under the last three administrations. As of early 2026, immigrants were filing an average of more than 200 habeas petitions daily, and over 11,110 petitions were filed in the opening weeks of 2026 alone — already surpassing the roughly 9,250 filed in all of 2025. In Minnesota, the impact has been especially dramatic. Habeas filings jumped from about a dozen in all of 2024 to more than 700 in just two months. U.S.
Attorney Daniel Rosen said his staff were “continuously working over time,” with the civil division operating at only 50% capacity. In the Western District of Texas, the U.S. Attorney stated his office was “forced to shift its already limited resources from other pressing and important priorities.” The judiciary has largely pushed back. Over 300 federal judges have ruled against the administration’s detention policies. Only 14 have upheld them. That lopsided record suggests the mass detention approach is generating enormous legal liability and court congestion while producing unfavorable rulings for the government in the vast majority of cases.

What the Gun Prosecution Decline Means for Public Safety
The practical impact of fewer federal gun prosecutions depends on where you live. Federal cases typically target the most serious offenders — repeat felons caught with firearms, straw purchasers supplying illegal markets, and traffickers moving weapons across state lines. When those cases do not get made, state and local prosecutors can sometimes pick up the slack, but they generally lack the resources, sentencing leverage, and cross-jurisdictional reach that federal prosecution provides. National shooting deaths through September 30, 2025, stood at 11,197, down 14% from the same period in 2024, with 20,425 nonfatal shooting injuries recorded.
Gun violence was already on a downward trend before the enforcement pullback, which makes it difficult to attribute changes in crime statistics directly to the federal prosecution decline. However, criminologists and law enforcement officials have warned that the effects of reduced federal enforcement tend to be lagging — gun trafficking networks that go uninvestigated now will supply weapons that show up in crimes months or years later. The comparison to consider is this: federal gun prosecutions serve as a deterrent and disruption mechanism that operates differently from local policing. Losing that layer does not immediately spike the murder rate, but it removes a critical tool that cities like Baltimore, New Orleans, and Milwaukee have relied on to target the most dangerous armed offenders.
ATF Budget Cuts and the Future of Firearms Regulation
Beyond the temporary reassignment of agents, the proposed ATF budget threatens to make the enforcement collapse permanent. Cutting 550 of 600 firearms license investigators would leave the agency functionally unable to conduct routine compliance inspections of gun dealers, let alone pursue revocations against dealers who repeatedly sell weapons that end up at crime scenes. The zero-revocation record in the first four and a half months of 2025 is a warning sign. Gun dealers who falsify records, sell to straw purchasers, or fail to report missing inventory have historically been a significant source of illegally trafficked firearms.
Without inspectors to identify those dealers and investigators to build cases against them, the pipeline from licensed dealers to the illegal market operates with virtually no federal oversight. This is a structural change, not a temporary disruption. Even if agents are eventually reassigned back to ATF duties, the institutional knowledge lost through the 40% increase in investigator departures will take years to rebuild. Training a federal firearms investigator is not a quick process, and the cases they were working — often multi-year investigations into trafficking networks — cannot simply be picked up where they left off.

The Drug Enforcement Collapse Nobody Is Talking About
The gun enforcement story has gotten some attention, but the parallel collapse in federal drug prosecution has been largely overlooked. With approximately 75% of DEA agents diverted to immigration work, federal drug prosecutions have hit their lowest level in decades. This is happening while the administration simultaneously declares fentanyl a national emergency and uses it as a justification for border enforcement.
The irony is difficult to overstate. The agents who investigate cartel distribution networks inside the United States — tracing supply chains, flipping cooperators, building RICO cases — are instead processing immigration paperwork. A fentanyl trafficking organization operating in a major American city faces meaningfully less risk of federal prosecution today than it did two years ago, even as the political rhetoric around drug trafficking has intensified.
Where This Goes From Here
The tension between immigration enforcement and all other federal law enforcement priorities is not sustainable at current levels. Courts are already buckling, with more than 300 federal judges ruling against the administration’s detention approach. The habeas petition volume shows no sign of slowing — the daily filing rate in early 2026 exceeds anything the federal court system was designed to handle.
If the proposed ATF budget cuts go through, the firearms enforcement infrastructure will be damaged in ways that outlast any single administration. Rebuilding investigative capacity, restoring dealer oversight, and restarting abandoned multi-year cases will require years of sustained funding and hiring — assuming a future administration chooses to make those investments. In the meantime, federal gun and drug enforcement exists largely on paper in many parts of the country, whatever the official talking points may claim.
Conclusion
The Trump administration’s decision to redirect 23,000 federal officers to immigration enforcement has created a cascading failure across multiple areas of federal law enforcement. Gun prosecutions have dropped significantly in nearly half of all federal court districts, ATF has effectively stopped policing gun dealers, drug enforcement is at historic lows, and federal courts are drowning in habeas petitions that exceed the combined total of three prior administrations. These are not partisan claims — they are documented in federal court filings, agency records, and DOJ statistics.
The question going forward is whether the public and policymakers will recognize the tradeoffs that were made without their explicit consent. Every federal agent reassigned to immigration is an agent who is not investigating gun trafficking, drug distribution, cybercrime, or financial fraud. Every prosecutor drafting responses to habeas petitions is a prosecutor not building a case against an armed felon or a fentanyl distributor. These choices have consequences, and those consequences are now showing up in the data.
Frequently Asked Questions
Have federal gun prosecutions actually declined under the Trump administration?
Yes. Gun prosecutions dropped more than 10% in 40 of 94 federal court districts in 2025. In Maryland, gun charges fell 32% to the lowest level in at least 25 years.
How many ATF agents have been reassigned to immigration enforcement?
About 80% of ATF special agents have been reassigned to immigration cases. Nearly 1,200 agents — roughly half the agency’s workforce — spent at least some time on immigration duties in 2025.
Are other federal agencies besides ATF affected?
Significantly. Approximately 23% of FBI agents, 75% of DEA agents, 33% of U.S. deputy marshals, and nearly all Homeland Security Investigations agents have been diverted to immigration enforcement.
Has gun violence increased as a result of reduced federal enforcement?
National shooting deaths through September 2025 were actually down 14% from 2024. However, experts warn that the effects of reduced federal enforcement tend to lag, as uninvestigated trafficking networks continue supplying weapons for future crimes.
What is happening with habeas corpus petitions in federal courts?
Over 18,000 habeas petitions have been filed by detained immigrants — more than the last three administrations combined. In early 2026, immigrants filed more than 200 petitions daily, and over 300 federal judges have ruled against the administration’s detention policies.
Is ATF still conducting oversight of gun dealers?
ATF did not revoke a single gun dealer’s license in the first four and a half months of 2025, putting it on pace for a 90% drop from Biden-era levels. The proposed budget would cut 550 of 600 remaining firearms license investigators.
