近年來國內社會治安問題急速惡化，犯罪案件層出不窮，除了總體犯罪數量、犯罪人口、犯罪指數上昇外，犯罪行為亦傾向暴力、凶殘化、文惡質化，不但個人財產不保，生創亦隨時可能成為潛在的犯罪被害不特定客體，可謂人人自危。因而，人心思治，犯罪防制工作乃成為重要的公共議題（public issues ），而負責處理此一議題的政府機關－警政署，亦似乎提不出一套有前瞻性的政策，以茲因應。

事實上，衡諸世界各國警政工作的發展，都有一個共同的趨勢，就是工作單純化、專業化。單純化就是把工作項目界在犯罪預防、犯罪偵查和交通整理上；而專業化就是實現以上三大主要任務有關的專業知識和技術的研究發展。

我國警察行政工作一向龐雜無章，予人有「不務正業」、「無所不管」的惡劣刻板印象，以致大在三大主要任務上大打折扣，使警察在犯罪防制上之功能無法發揮，民眾日常生活的安全感，也就無法確保。故現在已到了民眾必須共同來關心警察防制犯罪公共政策的時候，促使警察「除暴安良」的工作目標，早日完成。

本研究區分為六章：第一章緒論；第二章相關文獻探討；第三章研究途徑、概念架構與研究假設；第四章研究設計與實施；第五章調查結果之分析與討論；第六章結論與建議。

主要建議：

１．凡與警察主要任務的達成沒有直接關係的行政業務，應採「除警察化政策」（depolicing policy ），俾以符合警察行政專業分工的原則，並蘊育良好的警民關係。

２．警察行政集權須兼顧地方的需要，應採適度地方行政分權化政策（decentralizing policy ），俾以建立健全的警察文官體制，並強化和諧的警民關係。

３．凡阻礙警民關係和諧發展的不利因素，應採「除障化政策」（deimpening policy），俾以充分發揮警察犯罪防制的功能。

總之，上述三大警政政策（3-D police policy ）對警察犯罪防制功能之發揮有直接的影響，所以它應是有關當局規畫政策的主要方針。

The police in this country are currently being confronted with a broad spectrum of critical issues such as the deterioration and their aggravation of public order, the growth in the crime rate, foul play and evenbrutalization. In the long urn, the individual property and even life are left hanging in peril. Anyone, in fact, likely to be vulnerable to a prospective crime. While public issues focuses on crime prevention, repression and investigation, those in charge, the National Police Administration, seem unable to adequately address this critical situation at this time.

Most recently there has been a world-wide trend in law enforcement directed towards simplification and professionalism. The aim of simplificaton that police work should centre on crime prevention, investigation and traffic control. To achieve this, professional knowledge and technological development must be maximized through carefully planned research studies. This will ensure the three goals be fulfilled.

Law enforcement in this country is commonly accused of being inefficent and deviant from the major work. This, in turn, continues to hinder the achievement of the three main police goals and to threaten the security of people's daily lives. As the situation is worsening, the tmie is now for peoplw to get involved in making police public policy concerning crime prevention, repression and investigation.

The dissertation is divided into six chapters: Chapter I Concept, Chapter II Relative Literature Survey, Chapter III Aproach Framework and Hypotheses, Chapter IV Research Design and Practice, Chpater V Analysis and Discussion of Survey Research, Chapter VI Conclusion and Proposal.

Primary proposals as follows:

1. It is necessary to establish the depolicing policy in order to get rid of those administrative duties which are not essential to the achievement of the three main police goals and to agree with professionalism of law enforcement to stremgthen the relationship between the police and the community.

2. It is recessary to establish the decentralizing policy in order to meet the needs for local automony which is essential in setting up the system of local police commissioner nominated or agreed on by a local governor or magistrate and essential in promoting the relationship between the police and the community.

3. It is also necessary to establish the deimpeding policy which is both an obstacle and a detrimental to strengthening the relationship between the police and the community and to fulfilling the three main police duties.

In summary, the above "three--D police policy, depolicing, decentralizing, diempeding has a directtigation functions. As such, it should be the guideline for the authorities in their formulation of future police policy.
