Operation False Positive is the name Marcus uses for his first attack against the DHS. It requires Marcus and others to jam identification cards and traveler's passes to create mass chaos, leading the DHS to believe that normal travelers are guilty of some type of abnormality. This not only causes hyteria in the streets but in school as well.... and Marcus is overjoyed when his father is pulled over driving his car.... not once, but twice, in one trip. In context, Marcus believes that this attack will throw the DHS and keep them so busy that they won't be able to quickly isolate threats. The last part of your question calls for your opinion.
