A number of advances in information technology, such as surveillance cameras an satellite-based systems that can pinpoint a person's physical location, provide amazing new data-gathering capabilities. However, these advances can also diminish individual privacy and complicate the issue of how much information should be captured about people's private lives. Advocates of advanced surveillance technology argue that people have no legitimate expectation of privacy in a public place and thus Fourth Amendment privacy rights do not apply. Critics raise concerns about the use of surveillance to secretly store images of people, creating a new potential for abuse, such as intimidation of political dissenters or blackmail of people caught with the "wrong" person or in the "wrong" place. Critics also raise the possiblity that such technology may not identify people accurately. Since there are few legal limitations to the surveillance of private citizens by industry, could the government contract surveillance to private companies? Would this be legal? Would it be desirable? Should law enforcement be involved? Should donors be informed? Discuss your answers
