In Chapter Seven, Marcus challenges a new technique being used by the police and DHS to locate criminals. He is extremely angry about the way the attack affects his privacy, and he actively works against it by scrambling the information on people's identification cards. In doing this, he makes it seem as if everyone in the city has abnormal behavior. Do I think it's acceptable that his tampering with other people's cards wreaks havoc on the city? This calls for your opinion. In my opinion, he is utilizing the only method he has to induce change and stand up for his beliefs. Civil rights and privacy are a very important part of the American identity. On the other hand, I wouldn't want to be the person who is hauled in for questioning.
