A Comprehensive Study on"National Security"and"Civil Liberties"in the United States

我们历史地研究和考察了美国反恐措施的发展。在此基础上，我们分析了国家安全需要与公民自由保护之间的现实张力和理论张力。作为这项研究的结果，我们发表了一些文章，分析了美国反恐措施的各种法律和政治问题，如“明确和当前的危险”概念、勃兰登堡标准、总统权力、紧急状态权和刑事调查程序。

We studied and examined the development of anti-terrorism measures in the United States historically. Based upon the knowledge, we analyzed both the practical and the theoretical tension between the need for the national security and the protection of civil liberties. As a result of this study, we have published articles which analyzed various legal and political issues of anti-terrorism measures in the United States, such as the concept of"Clear and Present Danger", the Brandenburg standard, the Presidential Powers, the Emergency Powers, and the criminal investigation procedures.
