美国白宫在南草坪举办UFC格斗赛，拉开美国建国250周年庆祝活动序幕的次日，联邦调查局局长卡什·帕特尔宣布，执法人员挫败了一起针对该活动的袭击阴谋，图谋者计划使用无人机和狙击手袭击特朗普等人。
如今两周过去，多名官员告诉美国有线电视新闻网（CNN），联邦和地方执法部门肩负起保卫华盛顿特区复杂的独立日假期安保任务，相关细节仍在敲定中，各机构都面临后勤协调难题。
独立日前三天，活动主办方公布了活动日程，包括每日下午起每小时安排的飞行表演，以及一场从傍晚开始、以特朗普发表演讲和烟花秀收尾的晚间活动。近日这两项活动的时间都已作出调整。
本周早些时候，由于华盛顿特区庆祝活动的时间表迟迟未能明确，负责特朗普安保的部分官员陷入困扰，他们难以敲定细节以制定全面安保计划。
消息人士称，由于每项活动的举办时间尚未敲定，安保部署细节一度陷入停滞，但现有安保基础设施可应对临时调整。
本周早些时候，在华盛顿特区市长穆里尔·鲍瑟于周一宣布大型烟花秀将于7月4日晚11点才开始后，主办方随即改变计划，就连特朗普的演讲时间也悬而未决。
此后，特朗普的演讲被调整至晚间更早时段，烟花秀也随之改期。
多名参与安保策划的官员告诉CNN，尽管面临针对特朗普的新一轮袭击风险，以及始终存在的独狼式袭击威胁，但华盛顿特区有能力妥善保障这类大型活动的安全。
联邦机构还将协助保卫美国各地多场独立日庆祝活动，包括波士顿、加利福尼亚州、宾夕法尼亚州和纽约的相关活动。
帕特尔周三重申，目前没有针对美国任何一场独立日活动的可信威胁，包括华盛顿特区的活动。
“具有国家和历史意义的活动会吸引大量民众，且具备象征重要性，因此可能成为各类威胁行为者的目标。”一份提前一周向全美警方共享的联邦执法通报中写道。
该通报还警告称，“受意识形态动机或非意识形态动机驱使的个人，可能发动暴力袭击或试图制造恐慌，以凸显一国安全体系的漏洞。”
“在大型安保方面，华盛顿算是个‘特殊案例’。”一名参与独立日安保策划的联邦执法人员告诉CNN，“这里所有人都深谙此类活动的安保流程。从国情咨文演讲、就职典礼到总统葬礼，这类活动在这里已是常态。”
“这些活动是安保等级最高的场合，”一名听取了安保策划简报的联邦官员告诉CNN，“它们从设计之初就按最高标准打造。”
近期，一名手持霰弹枪的男子图谋在白宫记者协会晚宴期间暗杀特朗普，这一事件检验了现有安保体系。据检方称，该男子突破特勤局安保防线，开枪打伤一名警员后被制服。
检方称，该男子当时与晚宴主办方同住一家酒店，并花时间勘察了前往晚宴举办宴会厅的最佳路线。
负责并统筹本次独立日活动安保的特勤局，将与联邦调查局、大都会警察局及其他联邦和地方警方协同作战，既要保障特朗普的飞行表演安全，还要持续维护国家广场上的“伟大美国州博览会”——所有活动最终将以一场时长45分钟、耗资85万美元的烟花秀落幕。
本月以来，联邦执法机构已处于满负荷运转状态，为今年举办世界杯的多座城市提供实体和网络安保、反无人机系统、拆弹小组及其他资源。
两名听取相关简报的联邦官员告诉CNN，这些世界杯安保部署还延误了联邦对美国国内其他事件的响应速度，包括炸弹威胁和其他紧急求助电话。
近期就有一例案例：一些联邦拆弹技术人员因被调往世界杯安保现场，无法及时回应移民海关执法局办公室外的可疑包裹警报。一名官员告诉CNN，尽管出警时间比平时更长，但最终确认该包裹并无危险。
随着世界杯赛事继续进行、参赛队伍陆续淘汰，本周比赛场次将大幅减少，但联邦机构仍将在全美部署安保力量，一方面保护前来观赛的外国政要和赛事本身，同时兼顾美国国庆日的庆祝活动安保。
过去几年里，特朗普多次险些被持枪男子袭击。最近一次是在今年早些时候，特勤局人员及时阻止了一名携带上膛霰弹枪的男子冲向特朗普出席的记者晚宴。
在华盛顿250周年庆祝活动首日的演讲中，特朗普的安保等级显著提升：现场设置防弹玻璃保护总统，搭建帐篷作为周边屋顶和制高点的视觉屏障，并且缩短了总统车队与舞台之间的距离。
一名参与安保策划的执法官员告诉CNN，7月4日的活动将采用同样的安保措施，并补充称“安保强度将超过上周的总统演讲活动”。
华盛顿特区拥有全美所有城市中最严格的空域管制。两名执法官员告诉CNN，由于这里部署了美国国土安全部、联邦调查局和特勤局等机构最先进的反无人机技术，或许是应对潜在无人机入侵准备最充分的城市。
“仍有可能发生意外，”一名参与安保策划的联邦官员告诉CNN，“但要说哪里最不容易出事，华盛顿或许是准备最充分的地方，就算不是第一，也名列前茅。”
尽管在美国市场上，易于购买且可携带致命载荷的无人机威胁持续增长，但美国尚未发生过大规模无人机袭击事件。
在此次白宫UFC格斗赛袭击阴谋案中，根据相关案件的法庭记录，该组织实施任何计划的能力都受到了极大限制。
起诉书显示，该组织所谓的策划范围有限，尽管数名成员持有枪支，但目前尚不清楚他们是否采购了无人机或爆炸物。目前已有8人因该调查被捕。
在一份起诉书中，被告告诉警方，尽管他曾向组织成员宣称自己会制造无人机，但实际上他并不懂如何建造。起诉书称，该组织的一名成员、所谓的头目曾给被告一台3D打印机用于制造无人机，但被告声称自己只是想要一个朋友和免费的3D打印机。
国庆假期期间，联邦和地方机构将部署无人机和反无人机技术，包括针对依赖无线电频率控制的基础民用无人机的干扰技术。
但专家此前警告CNN，市场上售价仅500美元的部分无人机采用了不同的控制系统，以现有技术无法对其进行干扰。针对这类无人机，联邦机构采取了其他应对手段，包括部署拦截网、使用己方无人机拦截以及发射弹体。
这些专家还告诉CNN，即便是探测特定类型的无人机也是一项挑战，部分机构已开始部署多种无人机侦测技术，包括可识别无人机螺旋桨嗡嗡声的音频和音调系统。
不过，华盛顿特区空域一直处于严密监控之下，加上本次飞行表演和安保措施，多个机构将对空域实施全方位监测。
Securing America’s 250: Law enforcement faces shifting plans and World Cup demands
2026-07-02T10:00:28.635Z / https://www.cnn.com/2026/07/02/politics/america-250-security-july-4
The day after the White House kicked off celebrations for America’s 250th birthday with a UFC fight on the South Lawn, FBI Director Kash Patel announced that law enforcement had thwarted a plot to attack the event using drones and snipers to target Trump and others.
Now, two weeks later, federal and local law enforcement are tasked with securing a complex July Fourth holiday in the nation’s capital, details for which are still being ironed out, with logistical headaches spreading across agencies, multiple officials told CNN.
Three days before the holiday, planners sent out a schedule of the events, including planned fly-overs every hour starting in the afternoon, and an evening of programs that start in the late afternoon and end in a speech from Trump and a fireworks show. The timing for both has been shifted around in recent days.
Earlier this week, the lack of a clear schedule for the DC celebration caused headaches for some of the officials managing Trump’s security as they tried to nail down details to form a comprehensive plan.
Without a firm plan for when each event will be held, details about how to deploy security were briefly in limbo, but the infrastructure allows for flexibility in last-minute changes, sources said.
Even the timing of Trump’s speech was up in the air earlier this week when planners reversed course after DC Mayor Muriel Bowser said Monday that the large firework show wouldn’t start until 11 p.m. on July Fourth.
Trump’s speech has since been moved to earlier in the evening, and with it the fireworks show.
Despite looming concerns of yet another attempt on Trump’s life, as well as the ever-present lone wolf threat, Washington, DC, is well positioned to secure these sorts of large-scale events, several officials involved in the planning told CNN.
Federal agencies will also be helping protect several other July Fourth celebrations across the US, including in Boston, California, Pennsylvania and New York.
Patel reiterated Wednesday that there was no credible threat against any of the nation’s July Fourth events, including in DC.
“Events of national and historical significance could be appealing targets for a range of threat actors, due to both the large crowds they draw and their symbolic importance,” a federal law enforcement bulletin shared with police agencies around the US said in the week ahead of the national holiday.
The bulletin also warned that “ideologically and non-ideologically motivated individuals could conduct violent attacks or seek to instill fear as a way of highlighting the vulnerabilities in a country’s security systems.”
“DC is kind of a unique animal when it comes to” large-scale security, one federal law enforcement involved in the security planning for July Fourth told CNN. “Everybody here already knows how to do these. From the State of Union address, inaugurations” and presidential funerals, “these are regular events that happen here.”
“They’re the most secure events,” a federal official briefed on the planning told CNN. “They’re designed that way. The highest level that you can get.”
That security was recently tested when a man armed with a shotgun was able to plot what prosecutors say was an assassination attempt on Trump during the recent White House Correspondents’ Dinner. The man was able to rush through Secret Service security, shooting one officer before being detained, prosecutors say.
They say the man had stayed in the same hotel as the event and spent time casing out the best routes to the ballroom where the dinner was held.
The Secret Service, which is leading and managing the July Fourth event, along with the FBI, Metropolitan Police, and other federal and local police, will be juggling security for Trump’s airshow, and the continued “Great American State Fair” set up on the National Mall — all culminating in a 45-minute, $850,000 fireworks show.
Federal law enforcement agencies have already been stretched thin this month, providing everything from physical and digital security to anti-drone systems, bomb squads and other resources across cities hosting this year’s World Cup.
Two federal officials briefed on the matter told CNN those deployments have also delayed federal responses to instances around the US, including bomb threats and other emergency calls.
In one recent instance, some federal bomb technicians were unable to respond to a suspicious package outside an ICE office because they had been deployed to the World Cup. While it took longer than usual to deploy, one official told CNN, the package was ultimately determined not to be dangerous.
While the number of World Cup matches will drop drastically this week as the tournament continues and countries are eliminated, assets will still be deployed across the states as federal agencies protect foreign dignitaries coming to the matches, the matches themselves, and America’s birthday celebrations.
In several instances over the last few years, Trump has come close to a gun held by a man who wants to kill him. Most recently, Secret Service officers stumbled to stop a man — carrying a loaded shotgun — from rushing the press dinner Trump attended earlier this year.
Trump’s security was notably heightened during a speech he gave in the first days of the capital’s 250 celebration, with bulletproof glass protecting the president; tents positioned as visual barriers to nearby rooftops and vantage points; and a shorter distance between the motorcade and stage.
Those same protective measures are expected to surround the president on July Fourth, one law enforcement official involved in the planning told CNN, adding that it would include “even more security” than last week’s speech from the president.
Washington, DC, has the most restricted airspace for any city in the US. Because it houses agencies with the most anti-drone technology — including the Department of Homeland Security, FBI and Secret Service — it is perhaps the best prepared city for any potential drone incursions, two law enforcement officials told CNN.
“Something could still happen,” one of the federal officials involved in security planning told CNN. “But I think of all places to have that happen, DC is probably better — as well prepared as any place else, if not more so.”
While the threat of drones, easily purchased and capable of carrying deadly payloads, continues to grow in the US, the country has yet to see a large-scale drone attack.
In the White House UFC fight case, the group’s ability to execute any plan appeared to have been heavily limited, according to court records in the cases.
The extent of the group’s alleged planning was limited, and while several did have firearms, indictments say, it’s unclear if any drones or explosives were procured. Eight people have been arrested in the investigation.
In one indictment, the defendant told officers he didn’t know how to build drones despite telling members of the group he could. One member and alleged leader of the group gave the defendant a 3-D printer to build drones, but the defendant claimed he just wanted a friend and free 3-D printer, the indictment says.
Federal and local agencies will have drones and anti-drone technology deployed during the holiday, including jamming technology for more basic, hobby drones that rely on radio frequencies to control.
But experts have warned CNN drones can be purchased for as little as $500 that use a different system which, with current technology, can’t be jammed. For those drones, federal agencies have different methods — including deploying nets, using drones of their own, and firing projectiles.
Even detecting certain drones can be a challenge, those experts told CNN, and certain agencies have begun deploying a wide array of drone-spotting technology, including systems that listen for the audio and pitch of a drone’s buzzing blades.
DC, however, is a closely watched airspace and, given the airshow and security measures, will be heavily monitored by multiple agencies.
