Which best describes Marcus' tone in this excerpt from Little Brother.
I'm 17 years old. I'm not a straight-A student or anything. Even so, I figured out how to make an Internet that they can't wiretap. I figured out how to jam their person-tracking technology. I can turn innocent people into suspects and turn guilty people into innocents in their eyes. I could get metal onto an airplane or beat a no-fly list. I figured this stuff out by looking at the web and by thinking about it. If I can do it, terrorists can do it. They told us they took away our freedom to make us safe. Do you feel safe?
