Years after 9/11: The attacks that changed U.S. homeland security forever - [your]NEWS

Nearly 3,000 people were killed in the Sept. 11, 2001 attacks, and the fallout reshaped U.S. homeland security with a wave of federal changes aimed at preventing a repeat. The article highlights the creation of the Transportation Security Administration (TSA) in December 2001, ending the pre-9/11 reliance on privatized screening by companies contracted by airlines. It also notes that aviation security rules before 9/11 did not prohibit knives with blades under four inches and that the 2004 9/11 Commission found checkpoint screening often failed to detect items and relied on flawed “layers” of defense. The piece also covers the Department of Homeland Security (DHS), describing how decentralized and poorly coordinated efforts limited threat response, according to the commission.
