Executive summary

ICE’s mission and practice are shaped by legal prioritization, limited resources, and shifting agency focus, which helps explain why many interior arrests are not of people with violent murder convictions; public data and multiple analyses show the share of detainees and removals who have violent convictions is small and fell under the most recent Republican administration compared with the prior Democratic one [1] [2] [3]. Comparisons are complicated by definitional choices (convictions vs. charges vs. prior arrests), diversion of personnel to border operations, and political messaging that often overstates the share of “dangerous” offenders targeted [4] [5].

1. ICE’s legal priorities and why “dangerous murders” aren’t the entire focus

Federal law and DHS guidance require ICE to prioritize certain removable noncitizens, but those priorities do not translate into an ability to arrest every removable person: courts and successive administrations have acknowledged the executive branch cannot remove all removable noncitizens, so ICE uses prioritization criteria (criminal convictions or charges are central, but other categories such as immigration fugitives and repeat re‑entrants are also targeted) [4] [1]. ICE’s public materials likewise state the agency conducts administrative arrests for removability while retaining authority to execute criminal warrants, which means many interior arrests are administrative, not the result of homicide or other violent‑crime investigations [1].

2. Resources, operational choices and diversion to the border

Analysts have noted that ICE agents and enforcement resources can be diverted to handle surges at the southwest border and to support CBP processing, which reduces interior enforcement capacity for tracking and prosecuting long‑term violent offenders inside communities [4]. MigrationPolicy and other outlets describe how resource constraints and Supreme Court rulings recognizing limits on enforcement capacity forced prioritization decisions in recent years [4].

3. What the data show about convictions and violent crimes under Biden vs. Trump-era enforcement

Multiple datasets and independent researchers have found that a sizable share of people ICE has arrested or detained have no criminal convictions; for example, contemporaneous reporting indicated under one administration a majority of ICE detainees lacked convictions and analyses found the share of arrests that were convicted criminals fell from about half to roughly a third under the subsequent administration, with the share convicted of violent crimes dropping from roughly 10% to the 5–7% range in various snapshots [6] [2] [3]. ICE and DHS spokespeople have disputed simple characterizations, asserting a high share of arrests involve people with convictions or pending charges, but those statements rely on different definitions and on counting pending charges and non‑violent offenses [5] [7].

4. Why many arrested or removed people lack murder or violent convictions

Analysts and civil liberties groups note ICE counts include people with final orders of removal, repeat re‑entrants, visa violators and those with administrative immigration violations — categories that can produce large arrest totals without violent convictions [1] [6]. Additionally, officials sometimes count people with pending charges as “criminal,” which inflates comparisons with convicted violent offenders; leaked datasets and third‑party compilations show substantial shares of detainees without convictions, and several independent analyses find relatively few detainees with violent‑crime convictions [8] [9].

5. Political messaging, accountability and competing agendas

Political actors on both sides use ICE statistics to support competing narratives: administration officials emphasize criminal removals to justify tough enforcement [7] [5], while researchers and watchdogs point to data showing many arrests are immigration‑only and that the proportion of violent‑crime convictions among detainees can be low [3] [2]. Congressional and advocacy statements also reflect partisan agendas, citing decreases or increases in convicted‑criminal removals to press policy claims, but those claims often rest on different time frames and counting rules [10] [6].

6. Bottom line

ICE’s limited ability to “focus” exclusively on people convicted of murder is rooted in law, resource constraints, shifting operational priorities and how the agency defines and reports “criminal” cases; public datasets and independent analyses show the proportion of detainees and removals with violent convictions is small and — depending on the period and methodology — was higher during parts of the Biden years than in comparable Trump enforcement snapshots, even as overall arrest numbers rose under the later administration [4] [2] [3]. Because available reporting uses differing definitions (convictions vs. charges vs. immigration violations) and periods, definitive statements about which president “deported more dangerous illegal immigrants” require careful, consistent metric choices that the public datasets do not always provide [6] [8].
