It is an important law because of the basic right that the american government is suppose to be for the people. It is the peoples right to rise up and fight for their personal freedoms if the government is mistreating them. The law is not about protection. If it was, than there many things we should outlaw as they are unsafe for americans and thousands of people each year die from.
Good points. So you don't help others because you need to help your own? Turning a blind eye can at times lead to more problems that might reach your own shores. You can't ignore and focus on your own in a "Global Society". It no longer works. Some view the military as an employment option. Spending money on bullets and airplanes also helps US citizens with work.
Are you trying to state that someone who endorses a car manufacture because they like the style of car should be held responsible if the brakes don't work correctly and there are more accidents as a result? Shouldnt the engineer be held responsible?
