I have been in places where I had much less freedom, and it doesn't bother me. Bin Laden is an evil man, but that doesn't mean the U.S. needed to spend 10 years and 10s or 100s of billions of dollars to kill him.
Well, should we have just left him alone to operate with impunity to plan more attacks that killed hundreds to thousands of innocents?
Also, when you quote 10s or 100s of billions of dollars to kill him, you are misrepresenting the situation. The vast majority of money and effort has been spent on disrupting Al Qaida operations and networks worldwide, not simply to kill one man. Its not simply a revenge crusade.
