The debate between privacy and surveillance has been thoroughly explored over the course of this semester. I would like to point out some points I believe haven't received due importance. In Citizenfour, it was revealed that the US government withheld information regarding the several programs which involved spying on its people, actively invading their privacy. This blatant disregard shows that the NSA doesn't view the right to privacy as the paramount and essential right it is. By giving them the right to use electronic surveillance, we reinforce this wrong belief and the abuses to the people's privacy will only intensify.
Secondly, I believe that the phrase "in the interest of national security " is extremely ambiguous and while it seems fairly obvious what counts as national security, it can be easily misused since it will be used to justify hypothetical crimes. Also, if the primary reason for electronic surveillance is national security, it won't be very effective since most situations involving national security are by foreign parties who would be aware of the locations with which the US has surveilling authority.
Lastly, it is important to consider the role played by privacy in our lives. Since privacy is primarily a natural right, it is hard to build legislation around it. In such cases, it is important to not give due importance to how it feels to lose privacy. People often argue that privacy is not as important as safety because they tend to poorly estimate the immense role played by their private space in their day to day life.
