前国会警察局长史蒂文·桑德周一给众议院议长南希·佩洛西和其他国会领导人发了一封八页长的信，信中提供了事件的详细描述导致了1月6日的骚乱，以及一个详细的事件时间表，因为他看到他们在那一天展开。
佩洛西立即呼吁Sund在1月7日下台。那天晚些时候，日落提交了辞职信。
美国广播公司新闻获得了这封信的副本CNN首次报道。
在信中，桑德说他知道这个情报导致并解释了他为什么依赖评估，以及他在事件发生之前和期间努力从国民警卫队和其他执法伙伴那里获得支持。
桑德写道:“完美的后知后觉并不能改变这样一个事实，即我们的集体经验或情报——包括联邦调查局、特勤局、国土安全部(DHS)和华盛顿特区大都会警察局(MPD)提供的情报——都没有表明1月6日可能会发生协调良好的武装袭击国会大厦的事件。”。
桑德说，情报显示，1月6日的事件将类似于11月和12月之前的两次选举后示威，他称之为马加一号和马加二号。尽管如此，他写道，评估包括“骄傲男孩、白人至上主义团体、反法西斯和其他极端主义团体的成员预计将参加1月6日的活动，他们可能倾向于暴力。”他继续说:“这与2020年12月12日的MAGA II事件的情报评估非常相似。”在之前的两次抗议中，都有“有限的暴力和/或对官员的伤害，以及有限数量的逮捕”。
“我们之前成功处理了两次重大的选举后示威活动，利用了一项基于情报评估的行动计划，该计划已被证明是可信、可靠和准确的，我们合理地假设2021年1月6日的情报评估也是正确的。”
根据Sund的说法，1月4日，国会警察情报和机构间协调司根据当前的情报信息，“评估”了所有预计在2021年1月6日星期三示威的团体发生非暴力反抗/逮捕行为的概率水平，从“遥远”到“不可能”。
桑德说，他指示该部门处于“全体待命”状态，这意味着每个宣誓官员都将工作。他还说，他启动了7个民间动乱部队排，约250名军官，其中4个排配备了头盔、防护服和盾牌。
1月5日，在暴徒袭击国会大厦的前一天，桑德主持了一个虚拟会议，与会者包括“来自华盛顿特区的12名高级执法和军事官员，包括联邦调查局，美国特勤局和国民警卫队。“会议的重点是1月6日的事件和1月20日的就职典礼，这已经被确定为国家特别安全事件。
桑德写道:“在会议期间，包括联邦调查局在内的任何实体都没有提供任何情报，表明数千名装备精良的武装叛乱分子将对美国国会大厦进行协调一致的暴力袭击。”。
桑德说，国土安全部从未发布过关于“暴力极端分子计划对美国国会大厦进行协调袭击”的威胁公告，并指出“美国特工署计划并确实在1月6日护送美国副总统到国会大厦，如果它认为国会大厦及其周围有暴力叛乱的威胁，显然不会这样做。”
在未遂叛乱的前夕，Sund说，他向他的领导团队发送了一封电子邮件，以确保所有官员都得到充分的通报，预计会有“漫长的一天、大规模的团体和可能包括暴力在内的冲突”。
桑德写道，当人群试图闯入大楼时，国会警察高官保护司准备疏散国会领导。国会警察“试图确保走廊安全，以防止暴徒进一步进入大楼”，并“开始疏散”国会议员到安全的地方。
桑德坚持认为，美国国会警察“没有失败”，该部门“没有人力、培训或能力”处理武装叛乱包括成千上万不惜一切代价致力于暴力和破坏的人。“他功不可没勇敢和英雄主义国会警察“人数众多，且胜算巨大”，设法保护国会议员的安全。
“整个情报界似乎都忽略了这一点，”桑德写道。
佩洛西1月15日宣布，她将任命退休的拉塞尔·奥诺雷中将(Russel Honoré)发布一份关于国会大厦安全的报告，他也是领导政府应对卡特里娜飓风的人。
佩洛西当时说:“我已经要求退役的拉塞尔·奥诺雷中将立即对安全基础设施、机构间流程以及指挥和控制进行审查。”"这位将军是一位受人尊敬的领导人，有处理危机的经验。"
桑德确实承认“一些系统崩溃了”，并且“违反政策或指令，甚至违背誓言的官员或官员需要被追究责任。”
最后，桑德在信中承诺，他“将尽我所能，尽我所能，帮助确保2021年1月6日的袭击不再发生”，他“随时准备、愿意并能够协助任何努力”。Former Capitol Police Chief Steven Sund says entire intelligence community missed signs of riot
Former Capitol Police Chief Steven Sund sent an eight-page letter to House Speaker Nancy Pelosi and other Congressional leaders on Monday, providing a detailed account of the events leading up to the Jan. 6 riots as well as a detailed timeline of events as he saw them unfold on that day.
Pelosi immediately called for Sund to step down on Jan. 7. Later that day, Sund submitted a letter of resignation.
ABC News obtained a copy of the letter, which was first reported by CNN.
In the letter, Sund said he knew about the intelligence leading up to the violent event and explained why he relied on assessments, as well as his efforts to secure support before and during the incident, from the National Guard and other law enforcement partners.
"Perfect hindsight does not change the fact that nothing in our collective experience or our intelligence – including intelligence provided by FBI, Secret Service, Department of Homeland Security (DHS) and D.C. Metropolitan Police (MPD) – indicated that a well-coordinated, armed assault on the Capitol might occur on Jan. 6," Sund wrote.
Sund said that intelligence indicated that the Jan. 6 event would be similar to two previous post-election demonstrations from November and December, which he described as MAGA I and MAGA II. Though, he wrote, the assessment included language that "members of the Proud Boys, white supremacist groups, Antifa, and other extremist groups were expected to participate in the Jan. 6 event and that they may be inclined to become violent." He continues: "This was very similar to the intelligence assessment of the Dec. 12, 2020, MAGA II event." During both of those previous protests there was a "limited amount of violence and/or injuries to officers, and a limited number of arrests."
"Having previously handled two major post-election demonstrations successfully utilizing an action plan that was based on intelligence assessments that had proven to be credible, reliable, and accurate, we reasonably assumed the intelligence assessment for Jan. 6, 2021, was also correct."
On Jan. 4, the Capitol Police Intelligence and Inter-Agency Coordination Division "assessed "the level of probability of acts of civil disobedience/arrests occurring based on current intelligence information," as "Remote" to "Improbable" for all of the groups expected to demonstrate on Wednesday, Jan. 6, 2021," according to Sund.
Sund said he directed the department to be placed on "all hands on deck" status, which meant every sworn officer would be working. He also said he activated seven Civil Disturbance Unit platoons, approximately 250 officers, with four of those platoons equipped in helmets, protective clothing and shields.
On Jan. 5, the day before the mob stormed the Capitol, Sund hosted a virtual meeting with "a dozen of the top law enforcement and military officials from D.C., including the FBI, U.S. Secret Service and the National Guard." The meeting focused on the Jan. 6 event and the Jan. 20 inauguration, which had already been established as a National Special Security Event.
"During the meeting, no entity, including the FBI, provided any intelligence indicating that there would be a coordinated violent attack on the United States Capitol by thousands of well-equipped armed insurrectionists," Sund wrote.
Sund said the Department of Homeland Security never issued a threat advisory about "violent extremists planning a coordinated attack on the U.S. Capitol" and noted that the "U.S. Secret Service planned to and did escort the Vice President of the United States to the Capitol on Jan. 6, which it obviously would not have done if it believed there to be a threat of a violent insurrection at the Capitol building and on its grounds."
On the eve of the attempted insurrection, Sund said he sent an email to his leadership team to ensure that all officers were fully briefed to expect a "long day, large groups, and clashes that could possibly include violence."
As the crowd was attempting to breach the building, Sund wrote, the Capitol Police Dignitary Protection Division prepared to evacuate congressional leadership. Capitol Police "attempted to secure hallways to prevent the mob from advancing further into the building" and "initiated evacuations" of members of Congress to safe locations.
Sund maintained that the U.S. Capitol Police "did not fail" and that the department "does not have the manpower, the training, or the capabilities to handle an armed insurrection involving thousands of individuals bent on violence and destruction at all costs." He credited the bravery and heroism of Capitol Police officers who "outnumbered and against tremendous odds" managed to keep members of Congress safe.
"The entire intelligence community seems to have missed this," Sund wrote.
Pelosi announced on Jan. 15 she was appointing retired Lt. Gen. Russel Honoré, the same man who led the government response to Hurricane Katrina, to issue a report on Capitol security in relation to the riot.
"I have asked retired Lt. Gen. Russel Honoré to lead an immediate review of security infrastructure, inter-agency processes and command and control," Pelosi said at the time. "The general is a respected leader with experience dealing with crisis."
Sund did acknowledge that a "number of systems broke down" and that "officials or officers who violated policies or directives, or even their oath, need to be held accountable."
In closing, Sund pledged in the letter he "will do anything I can, and everything that is requested of me, to help ensure that an attack like Jan. 6, 2021, never happens again" and that he stands "ready, willing and able to assist in any effort."
