Americans are witnessing historic plunges in homicide rates. Nationally, homicides fell by 16% from 2023, equating to 631 fewer deaths across 29 major cities, according to the Council on Criminal Justice.

Colorado, while not keeping up with the national decline, has seen significant drops in key areas — notably Denver and neighboring Aurora, where homicides dropped 58% and 36% respectively in the first quarter of 2025.

This encouraging trend demands an honest examination of contributing factors. A compelling correlation exists between this drop in violent crime and the intensified federal border control, threats thereof, and deportations under the Trump administration.

U.S. Customs and Border Protection (CBP) data underscores a dramatic shift in border enforcement. In March 2025, CBP recorded the lowest southwest border crossings in history, with U.S. Border Patrol (USBP) apprehensions averaging 264 per day — a 94% decrease from March 2024’s 4,488 daily average.

In May and June, media reports claim the U.S. Border Patrol released zero illegal immigrants into the United States. All of this reflects a robust policy shift, with President Trump and DHS Secretary Kristi Noem emphasizing swift deportations for illegal border crossers.

ICE’s Enforcement and Removal Operations (ERO) have prioritized “worst first” deportations, targeting individuals with serious criminal convictions for homicide, gang-related offenses, and drug trafficking. Since January 20, ICE has arrested more than 10,000 illegal immigrants, many linked to transnational criminal organizations like Tren de Aragua and MS-13, with Colorado operations yielding nearly 300% more administrative arrests than in 2024.

The correlation between these deportations and declining homicide rates is striking, particularly in Colorado. Denver’s first-quarter homicide count fell from 24 in 2024 to 10 in 2025, while Aurora’s dropped from 11 to 7. I

Targeted removals of foreign prison gang members disrupt criminal networks that fuel violence. That’s a point echoed by John Lott Jr., president of the Crime Prevention Research Center, who notes that deporting criminal aliens reduces opportunities for violent crime. While correlation does not prove causation, the temporal alignment of intensified ICE operations and fewer homicides suggests a credible cause-effect scenario.

Critics may argue that immigrants, including those unauthorized, commit crimes at lower rates than U.S.-born citizens, as shown in Texas studies from 2012-2018, where undocumented immigrants had a homicide arrest rate of 1.9 per 100,000 compared to 4.8 for U.S.-born citizens. Yet, this overlooks the disproportionate impact of high-profile offenders.

ICE data indicates that 13,099 immigrants convicted of homicide were living outside detention as of September 2024, many undetected due to city and state sanctuary policies (Colorado has both) or incomplete criminal background data from countries like Venezuela. Targeting these high-risk individuals, as ICE has done in 2025, directly addresses this gap.

Declining homicide rates demonstrate that strategic enforcement works. By prioritizing the deportation of violent offenders, the federal government restores safety and order. The mere messaging of crackdowns on “the worst offenders” inspires foreign criminals to deport themselves before they are caught.

This is not about demonizing immigrants, most of whom are peaceful, but about protecting communities from a small but dangerous subset of immigrants who came here to exploit soft-on-crime “criminal justice reform” policies of the left.

As Colorado and the nation reap the rewards of a secure border, we must support policies that keep law enforcement empowered and our streets and sidewalks safe to roam.
