据哥伦比亚广播公司新闻获得的一封信件显示，两个国会委员会的顶尖民主党议员要求获取有关一名移民与海关执法局（ICE）特工的详细信息和记录，该特工于7月初在缅因州枪杀了一名哥伦比亚移民，议员们要求了解该特工的培训与背景审查情况。
加利福尼亚州众议员罗伯特·加西亚（Robert Garcia）和康涅狄格州参议员理查德·布卢门撒尔（Richard Blumenthal）就7月13日在缅因州比迪福德发生的致命枪击事件，向国土安全部（DHS）高级官员提出了一系列问题。加西亚和布卢门撒尔分别是众议院监督委员会以及参议院国土安全委员会常设调查小组委员会的排名成员（即少数党最高级别成员）。
25岁的哥伦比亚移民约翰·塞巴斯蒂安·杜兰·格雷罗（Johan Sebastián Durán Guerrero）遭枪杀一事，引发了全国范围内关于联邦特工执法策略的辩论。此前不到一周，休斯顿另一名ICE特工枪杀了一名墨西哥男子。
美联社援引与涉案特工亲属的采访报道称，枪击杜兰·格雷罗的ICE特工为戴维·布鲁耶特（David Brouillette），其亲属表示该男子有心理健康问题，且长期存在虐待和暴力行为。该媒体还报道称，布鲁耶特告诉亲属，他是去年被ICE聘用的。
在他们的信件中，加西亚和布卢门撒尔询问了负责联邦执法培训中心（ICE特工在此接受培训）的官员，布鲁耶特是否接受了特朗普政府去年为向驱逐行动队伍新增数千名特工而设立的精简培训课程。在遭遇反对声浪后，ICE于6月宣布将取消缩短后的培训课程，并要求参加过该课程的人员接受额外培训。
民主党议员们询问布鲁耶特是否仅通过为期四周的在线课程完成了ICE特工的入职培训，以及在他参加或完成所接受的培训前，是否对其进行了背景审查。他们还要求获取与布鲁耶特的培训和考试相关的记录，以及针对7月13日枪击事件的调查材料。
加西亚和布卢门撒尔还要求了解ICE的培训程序的更多信息，他们援引了今年早些时候一名前ICE教官转为告密者的证词，该告密者将特朗普政府时期该机构的培训程序描述为“不足、有缺陷且支离破碎”。
“部署未经培训、不合格的官员和特工上街所固有的危险，要求进行监督、问责和改革，”他们在7月30日写给联邦执法培训中心主任本杰明·哈夫曼（Benjamine Huffman）和首席顾问托马斯·休斯（Thomas Huse）的信中写道。
哥伦比亚广播公司新闻已联系国土安全部的代表，征求其对加西亚和布卢门撒尔所发信件的置评。
国土安全部尚未正式披露枪杀杜兰·格雷罗的特工姓名。该部门表示，7月13日枪击事件中，杜兰·格雷罗所驾驶的车辆“试图逃离现场，出于对公共安全的担忧，一名特工开枪射击”。
特朗普的边境事务专员汤姆·霍曼（Tom Homan）近日就布鲁耶特的过往问题受到质询。
霍曼在CNN节目中表示，如果相关报道属实，“我认为他本该从未通过背景审查”。
得克萨斯州和缅因州的两起致命枪击事件均发生在交通拦截过程中。两名受害者均为被指控非法入境美国的移民，但国土安全部承认，他们并非ICE此前行动的原定目标。
在杜兰·格雷罗于比迪福德遭枪杀几天前，已在美国生活35年的墨西哥移民洛伦佐·萨尔加多·阿劳霍（Lorenzo Salgado Araujo）在驾驶工作货车时被一名ICE特工枪杀。ICE声称萨尔加多·阿劳霍在交通拦截期间用货车作为武器，导致特工出于自卫开枪——但车内其他男子对此说法予以驳斥。
这两起枪击事件促使ICE短暂暂停车辆拦截行动，但特朗普介入后该暂停令被取消。
霍曼：“随身摄像机是正确选择”

Democrats in Congress demand training, vetting information on ICE agent who killed immigrant in Maine

The top Democrats on two congressional panels are demanding details and records about the training and vetting of an Immigration and Customs Enforcement officer who shot and killed a Colombian immigrant in Maine earlier in July, according to a letter obtained by CBS News.
California Rep. Robert Garcia and Connecticut Sen. Richard Blumenthal posed a series of questions to top officials at the Department of Homeland Security about the July 13 fatal shooting in Biddeford, Maine. Garcia and Blumenthal are the ranking members of the House Oversight Committee and the Senate Homeland Security Committee’s Permanent Subcommittee on Investigations, respectively.
The killing of 25-year-old Colombian immigrant Johan Sebastián Durán Guerrero, which occurred less than a week after a Mexican man was fatally shot by another ICE officer in Houston, reignited a national debate over the tactics employed by the federal agents carrying out President Trump’s crackdown on illegal immigration.
The Associated Press identified the ICE officer who shot and killed Durán Guerrero as David Brouillette, citing interviews with close relatives who described the officer to the AP as a man who struggled with mental health challenges and had a long history of abusive and violent behavior. The outlet reported that Brouillette told relatives he had been hired by ICE last year.
In their letter, Garcia and Blumenthal asked officials overseeing the Federal Law Enforcement Training Centers — where ICE agents are trained — if Brouillette had undergone a condensed training process that the Trump administration set up last year as it sought to add thousands of new agents to its deportation force. After backlash, ICE in June announced it would scrap the shortened curriculum and mandate additional training for those who participated in it.
The Democratic lawmakers asked if Brouillette had simply taken a four-week online course to be onboarded as an ICE officer, and whether a background check was conducted on him before he entered or graduated the training he underwent. They also demanded records related to Brouillette’s training and tests, and the investigation into the July 13 shooting.
Garcia and Blumenthal additionally requested more information about ICE’s training procedures, citing testimony earlier this year from a former ICE instructor-turned-whistleblower who described the agency’s training procedures under the Trump administration as “deficient, defective, and broken.”
“The dangers inherent in the deployment of untrained and unqualified officers and agents to the streets demand oversight, accountability, and reform,” they said in a July 30 letter to Benjamine Huffman and Thomas Huse, the director and chief counsel of the Federal Law Enforcement Training Centers, respectively.
CBS News reached out to representatives for the Department of Homeland Security seeking comment on the letter sent by Garcia and Blumenthal.
DHS has not formally disclosed the name of the officer who killed Durán Guerrero. It has said that a vehicle being driven by Durán Guerrero during the July 13 shooting “attempted to flee the scene and, fearing for public safety, an officer discharged his weapon.”
Tom Homan, Mr. Trump’s border czar, was recently pressed on concerns about Brouillette’s past.
If the reports are accurate, Homan suggested on CNN, “I don’t think he should ever have cleared vetting.”
Both fatal shootings in Texas and Maine occurred during attempted traffic stops. The victims of both shootings were immigrants accused of being in the U.S. illegally but who DHS has admitted were not the original targets of the ICE operations that preceded their killings.
Days before Durán Guerrero was killed in Biddeford, Mexican immigrant Lorenzo Salgado Araujo, who had lived in the U.S. for 35 years, was shot and killed by an ICE agent while driving his work van. ICE has claimed Salgado Araujo weaponized his van during a traffic stop, leading an officer to shoot in self-defense – an allegation contradicted by the other men in the vehicle.
The killings prompted ICE to institute a short-lived pause on vehicle stops, one that was scrapped after Mr. Trump intervened.
Homan: “Body cameras are the way to go”
