According to the Department of Homeland Security, which area is not their responsibility?

The Department of Homeland Security (DHS) is primarily focused on measures to safeguard the nation against threats like terrorism, manage border security, and enforce immigration laws. Their broad mission encompasses protecting the country from various risks, including natural disasters and terrorist attacks.

The area of protecting gun rights, however, does not fall under the DHS's responsibilities. Gun rights are generally governed by federal, state, and local laws, focusing on the regulation of firearm ownership, possession, and use. This domain typically involves agencies like the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) rather than the DHS, which is more concerned with national security and public safety in the context of threats. Thus, the correct answer accurately reflects the scope of responsibilities assigned to the Department of Homeland Security.
