美国移民海关总署（ICE）周四发布的数据显示，该机构羁押人数较1月的历史峰值下降了12%，截至3月底，这一下降主要由无犯罪记录人员的拘留数量减少推动。
此次下降发生在全美两党对明尼阿波利斯地区大规模移民执法行动的强烈反对、两名美国公民在当地被联邦特工杀害，以及国土安全部领导层洗牌之后。
这也是特朗普总统连任并启动前所未有的驱逐镇压行动以来的首次重大下降。该行动让所有在美国境内无合法身份的人都面临逮捕和拘留。4月第一周的数据显示，拘留人口的下降趋势仍在持续。
尽管人数有所下降，日均拘留人口仍处于历史高位，超过了拜登政府任期和特朗普首届任期的水平。移民海关总署报告称，3月日均拘留人数约为6.3万人，而1月约为7.2万人。
被移民海关总署拘留的人员涉嫌违反民事移民法规，例如非法越境或逾期滞留签证。与面临刑事指控或有前科的人员相比，因违反美国民事移民法规被拘留的非刑事罪犯此前是该机构羁押人数增长最快的群体。
但从1月到3月，无犯罪记录的被拘留者平均人数下降了21%，尽管他们仍是拘留群体中规模最大的一部分。同一时期，面临待决指控和有前科的被拘留者人数分别下降了5%和4%。
政府官员公开和私下均表示，在明尼苏达州的“地铁突袭行动”后，他们的移民执法战略在一定程度上发生了转变。
今年2月，特朗普告诉美国全国广播公司新闻，在移民海关总署和边境巡逻队在双子城行动中杀害美国公民蕾妮·古德和亚历克斯·普雷蒂后，政府可以在执法行动中“稍微采取更温和的方式”。
在这起死亡事件发生后，总统解除了格雷戈里·博维诺的大范围边境巡逻行动总指挥职务，该行动涉及远离美墨边境的主要城市，颇具争议。博维诺此后已从联邦政府退休。上个月，特朗普将前国土安全部部长克里斯蒂·诺姆替换为当时的俄克拉荷马州共和党参议员马克韦恩·马伦。
政府官员此前告诉哥伦比亚广播公司新闻，移民海关总署和边境巡逻队使用的一些激进战术已在政治上引发问题。特朗普任命白宫边境事务专员汤姆·霍曼负责结束“地铁突袭行动”，而非诺姆。官员们告诉哥伦比亚广播公司新闻，在霍曼的领导下，政府已放弃在主要城市开展大范围移民突袭行动，转而重新聚焦于逮捕有犯罪记录的移民。
马伦在3月的确认听证会上表示，他计划朝着类似的方向推进。
“我希望与市政当局合作，让移民海关总署更多地承担转运职责，而非充当一线力量，”他说，“如果我们回归仅与执法部门合作的模式，我们就会前往他们那里，从监狱中押解罪犯。”
马伦还表示，移民海关总署在进入住宅或商业场所前将使用司法搜查令，除非他们正在追捕进入这些场所的目标人物。今年早些时候，一名举报人披露，移民海关总署已授权特工在针对有驱逐令人员的行动中无需司法搜查令即可强行进入住宅，这与长期以来的政策和做法大相径庭。
移民海关总署代理局长托德·莱昂斯上个月在接受《波士顿环球报》采访时也暗示，在马伦的领导下，逮捕行动将采取不同方式。
“不会像明尼阿波利斯那样，”他在谈及新领导层领导下的执法行动时表示，“不会再像以前那样了。”
美国移民政策研究所的副研究员科琳·普策尔-卡瓦诺表示，现在判断战略是否发生永久转变可能还为时过早。
“这可能只是明尼阿波利斯事件和公众对移民海关总署战术抗议之后的一段过渡时期，”她告诉哥伦比亚广播公司新闻，“言辞上确实发生了转变，但我们确实知道这些逮捕行动仍在继续，只是不一定会以明尼阿波利斯那样备受关注、大张旗鼓的公开方式进行。”
根据“驱逐数据项目”通过《信息自由法》诉讼请求获得的移民海关总署数据，从2月中旬明尼苏达州行动结束到3月初，全美移民海关总署日均逮捕约1040人，其中约40%没有犯罪记录。
当被问及拘留人数下降是否代表系统性变革时，国土安全部发言人周日告诉哥伦比亚广播公司新闻：“从第一天起，国土安全部的执法部门就一直在兑现特朗普总统对美国人民的承诺，逮捕并驱逐犯罪性非法外籍人士，包括杀人犯、强奸犯、恋童癖者、帮派成员和恐怖分子。”
移民海关总署的数据显示，近几个月来该机构记录的附带逮捕人数有所减少。“附带”逮捕指的是在执法行动过程中逮捕原本不是行动目标，但被发现非法居住在美国境内的人员。
数据显示，今年年初超过四分之一的逮捕被标记为“附带逮捕”，到3月初这一比例已降至五分之一以下。移民海关总署自2025年8月起开始统一记录这一区别。
自那以来，绝大多数逮捕都被标记为针对性逮捕，尽管并不总是清楚移民海关总署如何确定抓捕目标。数据显示，在针对性行动中被捕的人员中约有三分之一没有犯罪记录。移民海关总署此前曾辩称，一些没有美国犯罪记录的移民可能在本国犯下过罪行，或者 otherwise 构成公共安全威胁，比如帮派成员。
“确切的新战略究竟是什么，仍有待观察，”普策尔-卡瓦诺说，“真正的考验将是未来几个月的情况，届时马伦部长将正式就职，国土安全部将进行重组并确定相关战略。”

ICE detained fewer non-criminals since Minnesota crackdown, driving a decline in detention population, data shows
April 13, 2026 / 6:00 AM EDT / CBS News
The number of people in Immigration and Customs Enforcement custody declined by 12% from a record-high in January to the end of March, data released by the agency on Thursday shows, driven largely by a decline in detentions of those without criminal records.
The drop follows the nationwide, bipartisan backlash to the massive immigration enforcement operation in the Minneapolis area; the killings of two American citizens at the hands of federal agents there; and a shakeup in Department of Homeland Security leadership.
It also marks the first major decline since President Trump returned to office and began an unprecedented deportation crackdown that has made anyone in the U.S. without lawful status subject to arrest and detention. Data for the first week of April indicates the detention population’s decline is continuing.
Despite the decline, the average daily detention population remains at historic high levels, above levels seen during the Biden administration and the first Trump administration. An average of about 63,000 people were detained each day in March, ICE reported, compared to about 72,000 in January.
Those detained by ICE are accused of civil immigration violations, such as crossing the border illegally or overstaying a visa. Non-criminal detainees accused of civil violations of U.S. immigration law were previously the fastest-growing group in ICE custody, compared to those with pending criminal charges or prior convictions.
But from January to March, the average number of detainees without criminal records dropped by 21%, although they are still the largest group in detention. Over the same timeframe, the number of detainees with pending charges and convictions declined by 5% and 4%, respectively.
Administration officials have signaled, both publicly and privately, that their immigration enforcement strategy has shifted to some degree following Operation Metro Surge, the operation in Minnesota.
In February, Mr. Trump told NBC News that the administration could “use a little bit of a softer touch” in enforcement operations after ICE and Border Patrol killed U.S. citizens Renee Good and Alex Pretti during the Twin Cities operation.
Following the deaths, the president removed Gregory Bovino from his post as Commander at Large of sweeping and controversial Border Patrol operations in major cities far away from the U.S.-Mexico border. He has since retired from federal service. Last month, Mr. Trump replaced former DHS Secretary Kristi Noem with then-Sen. Markwayne Mullin, a Republican from Oklahoma.
Administration officials previously told CBS News that some of the aggressive tactics used by ICE and Border Patrol agents had become politically problematic. Mr. Trump tapped White House border czar Tom Homan — instead of Noem — with winding down Operation Metro Surge, and officials told CBS News that under his direction, the administration had moved away from broad immigration sweeps in major cities and renewed focus on arresting immigrants with criminal records.
At his confirmation hearing in March, Mullin signaled he plans to move in a similar direction.
“Working with municipalities, I would love to see ICE become a transport more than the front line,” he said. “If we get back into simply working with law enforcement, we’re going to them, we’re picking up criminals from their jail.”
Mullin also said that ICE would be using judicial warrants before entering homes or businesses, unless they are actively pursuing someone who enters those places. Earlier this year, a whistleblower revealed ICE had empowered agents to forcibly enter homes, without judicial warrants, in operations targeting individuals with deportation orders, a marked departure from longstanding policy and practice.
ICE acting director Todd Lyons also suggested arrests would be carried out differently under Mullin in an interview with the Boston Globe last month.
“Not like Minneapolis,” he said of enforcement operations under new leadership. “Not like before.”
Still, it may be too early to tell whether there has been a permanent shift in strategy, said Colleen Putzel-Kavanaugh, an associate analyst at the Migration Policy Institute.
“It may be part of just a transitory time, following Minneapolis and following the public outcry of ICE tactics,” she told CBS News. “There has been a shift in rhetoric, but we do know that these arrests continue, they’re just not necessarily happening in sort of the high-profile, very flashy public ways like in Minneapolis.”
Nationwide, ICE arrested an average of about 1,040 people each day between mid-February, when the Minnesota operation ended, to early March, according to ICE data released in response to a Freedom of Information Act request lawsuit by the Deportation Data Project. About 40% did not have criminal records.
When asked whether the decline in the detention population represents a systematic change, a DHS spokesperson told CBS News on Sunday that “since Day One, DHS law enforcement has been delivering on President Trump’s promise to the American people to arrest and deport criminal illegal aliens including murderers, rapists, pedophiles, gang members, and terrorists.”
ICE data indicate the agency has been recording fewer collateral arrests in recent months. “Collateral” arrests refer to arrests of those who aren’t the original targets of an operation but found to be living in the U.S. illegally in the process of an enforcement operation.
More than a quarter of arrests at the start of the year were labeled “collateral,” compared to fewer than one-fifth by early March, the data show. ICE began recording this distinction consistently in August 2025.
The vast majority of arrests since then were marked as targeted, although it is not always clear how ICE determines who to target. Roughly one-third of those arrested in targeted operations lacked criminal records, the data show. ICE has previously argued that some immigrants without U.S. criminal records may have committed crimes in their native countries or may otherwise be public safety threats, like gang members.
“It remains to be seen what the new strategy is exactly,” Putzel-Kavanaugh said. “The real test will be what the next couple of months look like as Secretary Mullin settles in, as DHS sort of regroups and decides what that strategy is.”
