September 11 Attacks Killed Nearly 3,000 People, Shaping Homeland Security 25 Years Later

Nearly 3,000 people were murdered in the September 11, 2001 attacks that struck the World Trade Center, the Pentagon, and a Pennsylvania field, and the next day marked 25 years since the attacks shattered America’s complacency.

“Nearly 3,000 people were murdered.”

The RAND commentary frames homeland security lessons as a shift from the post-9/11 catalyst toward a “multi-hazard environment,” noting that “September 11 allowed leaders to overcome much of the resistance” even as it created a “patchwork of organizations working on homeland security.”

In Philadelphia, fire and police departments said the lessons learned on 9/11 continue to shape emergency response through specialized training, technology, coordination, and first responder safety.

Lt. Sean Carlin of the Cherry Hill Fire Department said, “New York, Philly, they all had collapse training. Cherry Hill, we didn't have any of that before 9/11,” while Michael LaBarr of the City of Camden described newer cameras and sensors that can help crews locate people trapped beneath debris.

Derrick Wood, chief of Penn Police and a former Philadelphia police inspector, said collaboration created after 9/11 includes the Delaware Valley Intelligence Center, calling it “a fusion center” where “All the agencies, their federal agencies, local and state, work together.”

Wood also said police training now includes subjects such as mental health awareness and trauma-informed response, adding, “We have more technology than we had before 9/11.”

ABC News

Across the country, the Associated Press reporting cited by ABC News found that at least 40 U.S. states expect or suggest that public schools address 9/11 in some way, including classroom teaching, a moment of silence, or other observances.

ABC News also reported that Arizona lawmakers decided in 2022 to require every public school to devote time on or around each 9/11 anniversary to “age-appropriate education” about the attacks, and that the requirement was later limited to seventh through 12th grades.

In the RAND commentary, Brian Jackson argued that “Congressional oversight remains diffuse,” and said “we need to stand together to tackle ongoing and emergent homeland security challenges.”

The Council on Foreign Relations describes the 25-year legacy of the “war on terror” as a shift that spurred military action in Afghanistan and Iraq and contributed to a hyperfocus on al-Qaeda and its affiliates, while warning that prevention must evolve beyond heavy-handed approaches.

“prevention through addressing the conditions conducive to violent extremism yields better results than military force.”

In that same CFR framing, the organization says violent extremism has been understood as a security threat requiring “hard security measures,” and it argues that “prevention through addressing the conditions conducive to violent extremism yields better results than military force.”

In Europe, European Commission President Ursula von der Leyen urged remembering the lessons of 9/11 and said, “In times of danger, our alliances matter, our unity matters, the values we choose to defend matter,” while also stressing that Europe “immediately knew which side to stand on” with NATO’s Article 5 activation.

Von der Leyen also said those who sought to spread fear “failed,” and paid tribute to “the almost 3,000 people who died in the attacks,” linking the consequences to “the importance of alliances and collective security.”

The voz.us essay adds that “Information is not the same thing as urgency,” and argues that serious threat assessments deserve “a hearing before the disaster, not a commemorative plaque after it.”
