Definition of privacy has changed by the changes and improvements in information and surveillance technologies. These changes and improvement need new legal decisions for new kinds of privacy invasions. This study explores the scope of privacy right, particularly when a technological surveillance has occurred by law enforcement agencies. It focuses in particular on increasing law enforcements' surveillance technologies and devices that have the potential to impact citizens' information privacy. These increasing changes in surveillance technologies have important implications both for law enforcements and citizens. This study also discusses increasing law enforcement surveillance for the public's security, changes of the laws that allow law enforcements to use new surveillance powers as a war on terrorism, and the citizens concerns of information privacy. A particular attention is given to the recent public opinion surveys which show citizens' increasing privacy concerns. Finally, a set of recommendations to figure out security-privacy debate and reduce the privacy concerns of the citizens is offered.

This study explores the underlying causes and deterrent control mechanisms of police misconduct in the United States. Outcomes of causes and control mechanisms constitute the basis for an applicable model for the Turkish National Police (TNP). Why is some police behavior deviate? What are the main determinants of police misconduct? Is police misconduct a result of sociological behavior and subcultural development within police organizations or a psychological behavior as an outcome of officers' personal traits? What are the control mechanisms for police misconduct? What are their strengths and weaknesses? Do they deter or not? Is there a control mechanism that deters better than others? What is the best deterrence model for the TNP?

Electronic commerce was expected to grow exponentially, but the actual rate of growth in recent years has been disappointing. Recent surveys of perceptions of the development of electronic commerce clearly focus our attention on the perception and fear of computer crime as the major cause of this disappointing growth pattern. The thesis critiques existing private law solutions to this problem and argues from a normative theory on “the commons” for the application of new public law enforcement solutions in the public trust, sanctions, and public coproduction of order. The thesis argues that given the failures of existing private law solutions to the problem, these public law enforcement solutions should be more effective, efficient, and more satisfactory.
