ICE continues to arrest large numbers of high-risk criminal aliens, but those arrests are a victory lap, not proof the border is secure. Large, publicized enforcement operations show the agency can find and remove dangerous actors inside the United States. At the same time the operational picture reveals systemic gaps that non-state actors exploit to move people, drugs, and materiel with impunity.

The problem is not ICE’s willingness to act. It is structural and procedural failures upstream and downstream of those arrests. Local noncooperation and process shortfalls routinely force ICE into higher-risk, lower-effectivespace. In multiple recent cases ICE was compelled to arrest convicted offenders on public streets because county officials declined to honor immigration detainers, creating unnecessary operational risk and wasting enforcement resources. That is exactly the kind of friction that lets dangerous people slip past timely screening and custody.

Those local frictions sit on top of longer-standing intelligence and screening gaps. A Department of Homeland Security Office of Inspector General audit found ICE’s screening protocol for identifying aliens who may be known or suspected terrorists had important limitations and compliance failures. The audit documented inconsistent implementation of the Known or Suspected Terrorist Encounter Protocol and noted ICE did not require continued screening of millions of noncitizens once they left custody. That creates a persistent, latent risk: a small number of undetected high-risk individuals can become a much larger public-safety problem over time.

Policy experiments intended to manage large migratory flows have introduced their own vulnerabilities. The Government Accountability Office review of supporter-based humanitarian parole processes between 2022 and 2025 found fraud risks and administrative weaknesses that reduced DHS’s ability to vet entrants and to pursue enforcement when parole conditions were violated. That is not academic. When parole systems are subject to deception, criminals and trafficking networks can send personnel or associates through legal-looking pipelines that sidestep border interdiction.

Meanwhile transnational criminal organizations have shifted tactics and business models to exploit precisely these seams. U.S. law enforcement and prosecutorial actions in 2024–2025 documented cartel-linked alien smuggling networks, profitable fuel and freight schemes, and direct use of migrant trafficking to monetize routes and launder revenue. In early 2025 the U.S. government formalized a strategy shift by designating multiple large Mexican cartels and violent transnational gangs as foreign terrorist organizations and specially designated global terrorists. Those moves recognized what investigators have said for years: cartels are not only drug suppliers, they are supply-chain managers, extortionists, and smugglers who weaponize migration and the humanitarian system to expand profits and influence. Those capabilities give them leverage to move people, drugs, and weapons while raising the operational cost for U.S. enforcement.

Put plainly: ICE can arrest high-risk criminal aliens in the interior. Arrests alone do not close the loop. Gaps in detention cooperation, intermittent screening, parole and humanitarian pathways that are not hardened against fraud, and cartel tactics that mix smuggling with other criminal commerce all create a resilient ecosystem that non-state actors exploit. Arrests should be the end of an evidence-driven sequence, not the start of another cycle of release, evasion, and reentry.

Operationally, this has four concrete consequences:

1) Tactical risk and resource drain. Forcing arrest operations into public spaces because local jails will not hold targets increases danger to officers and bystanders and drives up the manpower needed to effect a safe arrest.

2) Intelligence gaps become security gaps. If screening stops once custody ends or is inconsistently applied, ICE and partner agencies lose the ability to detect long-tail threats. The OIG findings are a cautionary record on how process failure translates into national security risk.

3) Legal and administrative pathways can be weaponized. Humanitarian parole and other expedited entry programs are necessary tools. If they are not engineered with rigorous vetting, audit trails, and post-entry monitoring, they become avenues for exploitation by smuggling networks. The GAO review highlighted exactly those vulnerabilities.

4) Smuggling networks will adapt. Designation of cartels as FTOs and the criminal prosecutions of cartel-linked smuggling networks illustrate an adaptive adversary that integrates trafficking, extortion, and logistical services. Law enforcement successes are meaningful. They do not remove the incentive structures fueling the trade.

What must change now. The recommendations are plain and operational.

  • Treat custody and screening as an end-to-end workflow. ICE, CBP, and DHS components must adopt policy and funding that ensures continuous, auditable screening for high-risk indicators from first encounter through removal. That means mandated periodic rescreening for certain risk categories and seamless classified network access for field agents where necessary.

  • Restore and standardize custody cooperation. Federal, state, and local leaders must create binding agreements that prioritize safety and intelligence-driven handoffs. Where local policy refuses cooperation, federal partners must have legally sound, surgically targeted avenues to secure custody that do not expose officers or the public. The current ad hoc response model is costly and unsafe.

  • Harden parole and humanitarian processes. Supporter-based parole and similar programs must integrate automated fraud detection, stronger identity verification, and mandatory post-entry monitoring tied to enforceable sponsor obligations. GAO’s review shows the cost of leaving those systems porous.

  • Follow the money and the routes. Designations and sanctions create prosecutable levers. Use them aggressively while sustaining interdiction and investigative capacity against smuggling networks that use migratory flows as cover. The DOJ and Treasury actions in 2024–2025 offer playbooks to disrupt cartel logistics.

  • Measure outcomes, not show rates. Arrest counts are a blunt metric. Measure reductions in recidivism, reductions in unvetted entries by risk cohort, and the time between identification and safe custody. Those metrics will expose whether enforcement translates into lasting mitigation.

ICE’s recent arrest operations prove the agency can find high-risk targets in the interior. They do not prove the system is secure. Until screening is continuous, custody handoffs are reliable, humanitarian channels are hardened, and cartel commerce is systematically disrupted, non-state actors will continue to exploit the seams. The fix is operational, not rhetorical. Fund the work. Standardize the processes. Hold partners to account. Do those things and arrests will mean more than headlines.
