Birth add Development of Homeland Security Law. The new Homeland Security Law Handbook provides a comprehensive reference book for business, industry, and government as well as those faced with the new legal and security issues raised by new public laws, a new regulatory framework, and a new Department of Homeland Security. Written by legal experts from four law firms, it covers the major issues involved with homeland security.

An analysis, summary, and political context of homeland security statutes and their subsequent regulatory mandates are also discussed. Part II includes detailed discussions of public safety issues, including aviation and transportation security, port security, and chemical security; the public health issues of bioterrorism and air, food, and water supply contamination; border and immigration concerns; cyber security; appropriations, grants, and contracts; insurance and workplace issues; and information and disclosure issues in audits. Part III covers the creation, mandate, and organization of the new cabinet department with its powers, practices, procedures, and responsibilities. Each of the four Directorates and their organization, function, major issues, and transitional challenges are also analyzed.
