what event led to establishing the department of homeland security answers.com
United States Department of Homeland Security The United States Department of Homeland Security (DHS) is a cabinet department of the United States federal government with responsibilities in public security, roughly comparable to the interior or home ministries of other countries. Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management.[3] It was created in response to the September 11 attacks and is the youngest U.S. cabinet department.
Immigration and Naturalization Service Referred to by some as former INS[2] and by others as legacy INS, the agency ceased to exist under that name on March 1, 2003, when most of its functions were transferred to three new entities – U.S. Citizenship and Immigration Services (USCIS), U.S. Immigration and Customs Enforcement (ICE), and U.S. Customs and Border Protection (CBP) – within the newly created Department of Homeland Security, as part of a major government reorganization following the September 11 attacks of 2001.
