Chapters 1-3 showed the beginnings of national security and the expansion and growth of national security. Chapter 4 shows national security actions and the steps to take to address a problem to solve it. Above all, DHS must understand and understand how to deal with an attack quickly and efficiently and put countermeasures in place in advance. DHS must be able to access the risks of any situation and must decipher the potential danger the situation could cause. When considering the many functions of the DHS, nothing could be more important than the ability to understand, thwart, or stop a man-made or non-man-made attack. First of all, Homeland Security studies the nature of the risk; this means that they study what is likely to happen in a given situation. The message explains risk as what can go wrong. A cigarette smoker runs a risk every time he lights up, and everyone runs a risk when they get into a car. DHS takes what it knows from previous circumstances to determine the reality of the risk; the department must also anticipate any attack even without prior knowledge of the circumstance. The main risk assessment questions are easy to understand, questions such as whether people will be injured or harmed. But when you look at Chapter 1 which asks the reader to delve deeper into why terrorists commit terrorism, that's when it's easiest to see DHS's skill at risk assessment. For example, if you understand that a terrorist attack could come from a radical Islamic terrorist; then you would understand the risk by understanding the reason behind the attack such as their religious holidays. The DHS uses a three-pronged method for risk assessment and these are threat, vulnerability and consequence. The Rand organization uses the......middle of paper......must collect information from citizens. The question is, how many freedoms are we willing to sacrifice to feel safe, when it becomes a slippery slope and more is taken away from us than we wanted. Is the price of security worth the price of freedoms? And do freedoms and liberties outweigh the price of security? Internal terrorism is causing much more serious damage than external terrorism, and the difficulty of stopping it has led to some undesirable results. There is no doubt that radical Islamic domestic terrorism will happen again, and when that happens how far will America go to stop it. Will domestic terrorism cause America to lose who we are? Or will we find new ways to fight the evil that is? Only the future will tell, but one thing is certain: we as citizens can do a lot to help and we must be strong in what we believe in..
