DHS has a role to monitor and control the borders and prevent border crossing. DHS must enforce laws and policies regarding immigration and illegal crossings. DHS must also respond to natural disasters and natural catastrophes. DHS must protect the US citizens from terrorist attacks, both foreign and domestic. The borders around the United States are not just on land but also on the surrounding waters and airspace. Monitoring of those traveling and moving commerce are a huge responsibility of the DHS. DHS protection allows for a striving tourist market and businesses.
Integrity is key for all employees of DHS to have, given we are dealing with the highest level of security for the nation. DHS must also react to domestic emergencies. DHS must investigate and respond to acts of threats and terrorism, as well as to enforce policies and laws regarding those that break immigration laws. The United States policymakers and congressional commissions realized there were multiple gaps that needed to be addressed in the intelligence community. There was a need for a Fusion Center and intelligence sharing among various agencies (LII, 2023).
The legal definition of hazards, includes man-made or technological and naturally occurring hazards that have the potential to damage human life. Objects are interchangeable with agents. When a hazard is from a direct result of human intervention then it is called a man-made hazard. Humans are not perfect; therefore, the human element opens up the possibilities of neglect and incompetence, which can lead to catastrophes. Human error can create billions of dollars in damage.
Examples could be a person throwing a cigarette out their car window and an entire forest being destroyed. A captain of a ship can miscalculate a route and sink an oil transport vessel. Errors in technology can also lead to disaster. A user may make a mistake and push the wrong controls and a ship may ram the pier. A technological hazard involves such dangers. Technology can miscalculate a flight pattern and a pilot might not notice they are flying into a precipice. Technology can also be hacked. Industry and technology have created a lot of pollution. Large power plants can let off radiation. Manufacturing plants and transport vessels and trucks can spill chemicals.
The United States experiences natural hazards each season, as the landmass is vast and there are various terrains, plus we have coastlines, fault lines, and a few volcanos. Natural hazards can lead to natural disasters coming from earthquakes, volcanic eruptions, tornadoes, hurricanes, excessive snow, hail, and rain, as well as floods and fires (CDHS, 2023).
