the conflict issues between freedom of expression and right of property in decriminalization of street culture

这项研究的目的是重新考虑所谓的涂鸦在言论自由的背景下的意义，而不是将其视为破坏或犯罪活动。作为一个案例研究，它涉及班克西，他是世界上最著名的涂鸦艺术家之一。基于班克西的历史和社会背景，考察班克西的活动与布里斯托尔市议会和公众舆论的态度之间是怎样的关系，以寻求涂鸦积极的一面。自20世纪70年代以来，涂鸦在世界各地出现，超越了文化的界限，具有一种普遍的街头文化风格。本研究立足于现状，试图重新界定文化上优越于财产权的言论自由权。

This research aims to reconsider the significance of so-called graffiti in the context of freedom of expression not considering it as vandalism or criminal activity. As a case study, it deals with Banksy who is one of most famous graffiti artists in the world. It examines, based on historical and social back ground of Banksy, what kind of relationship between activities by Banksy and the attitudes of Bristol City Council and public opinion in order to seek a positive side of graffiti.Graffiti has a kind of universal style of street culture because it is appeared all over the world beyond cultural boundaries since 1970s. Based on the present situation, this research tries to redefine the right of freedom of expression which is culturally superior to right of property.
