One of the things which stood out to me throughout the book Little Brother was how it was so easy for even everyday people to foil the security measures put in place by the Department of Homeland Security. One of my personal favorites was the "arphid cloners" which could replace all of the electronic information on things such as your credit cards and identification and replace that with those of someone else. A particular passage showcasing this was when Marcus' father came home after being pulled over and questioned twice. This occurred because his father had been all over town recently to many various places, or so the DHS thought from their surveillance data. His father really had done nothing wrong, but various people who had been "given" his identity were making it look like he had very odd travel patterns. This marked a turning point in the novel as Marcus' father finally realized that there were some potential downsides to all of this surveillance the DHS was performing.

This concept of messing with security goes far beyond this one specific type of exploit, and goes further than the book as well. Every method of surveillance must have some weakness, whether that be an ability to avoid it or to attack it with so much information it cannot sort through it all properly. That raises the question of how useful every surveillance implement of the government is in the real world. It is possible that any day a random group of people could come up with a method to completely mess with some form of NSA surveillance. However as seen in the book, it is us as citizens who are the ones that are punished when there are flaws in surveillance systems. Thus we must ask ourselves if we are truly comfortable continuing to give up some of our privacy to groups such as the NSA and if that our relinquishing some of our right to privacy is actually helping in any way at all.
