ICE and DHS do not publish a precise legal definition or checklist for who counts as “worst of the worst.” In practice, the label is a political/communications term used for a small subset of noncitizens whom ICE has arrested and who are:
The official “Worst of the Worst” pages say these people are those “convicted or accused of heinous crimes that put the American public at risk,” but they also show that DHS sometimes applies the label to people whose most serious offense is non‑violent or even just an immigration or low‑level drug/traffic charge, meaning the criteria are broad and discretionary rather than a narrow legal category.
Public documents do not explain exactly how ICE calculated the “more than 1,300% increase in assaults” and “8,000% increase in death threats” against its officers, or specify the baseline numbers used.
The only on‑record details are in ICE and DHS press materials, which simply state that ICE officers “have faced a 1,347% increase in assaults and an 8,000% increase in death threats” without giving the underlying counts, the years being compared, or the data source. Some secondary reporting says the comparison is to the last year of the prior administration, but ICE itself has not published a technical methodology. As a result, the exact measurement method and time period cannot be verified from available public information.
Most of ICE’s “worst of the worst” arrests involve people who have already been prosecuted and convicted in criminal court for the underlying offenses. The typical sequence is:
In those situations, the person usually faces immigration proceedings only, not new criminal charges, unless there is a separate federal immigration crime (like illegal re‑entry after removal) or a new offense discovered at the time of the ICE arrest.
The January 8, 2026 DHS press release does not name any specific ICE operation or task force for these particular arrests; it attributes them generically to “ICE” officers arresting “worst of the worst criminal illegal aliens.”
Based on ICE’s structure, arrests of removable noncitizens with serious convictions are normally carried out by Enforcement and Removal Operations (ERO) through field offices and programs such as the Criminal Alien Program, Fugitive Operations, and sometimes 287(g) jail partnerships, but the government has not tied these five named arrests to any one branded operation.
Coordination between local police/jails and ICE in serious felony cases generally happens through a mix of information‑sharing and formal agreements, and it varies by state and even by county:
So, in a serious felony case, ICE typically learns about the case through fingerprints, then either places a detainer or works directly with the jail or a 287(g) partner agency to take custody when the person is released from criminal custody.
Noncitizens arrested by ICE have important, but limited, rights in enforcement and removal proceedings:
These rights exist regardless of whether the person has prior criminal convictions, though people with certain serious convictions may have fewer options for relief from removal and may be subject to mandatory detention with no bond.
