The relationship between Chicano gangs, crime, the police, and the Chicano community is complex. Neither the problem of youth gangs nor the specialized police units created to cope with this problem arises in a social vacuum. Rather, both emerge from a particular historical structuring of social, economic, and political relations. This paper investigates how and why a moral panic arose concerning Chicano youth gangs in Phoenix in the late 1970s and early 1980s. A variety of qualitative and quantitative data from media reports, interviews, and juvenile court records are used to assess whether it was the actual behavior of Chicano youths or the social imagery surrounding them that formed the basis for the gang problem in Phoenix. I suggest that the image of gangs, and especially of Chicano gangs, as violent converged with that of Mexicans and Chicanos as different to create the threat of disorder. In addition, it was in the interests of the police department to discover the gang problem and build an even greater sense of threat so as to acquire federal funding of a specialized unit.  相似文献

In Morgentaler v. R., the Supreme Court of Canada struck down the abortion provisions in the Criminal Code. In a five to two split, a majority of the Supreme Court judges found that section 251 offended a pregnant woman's constitutionally protected right not to be deprived of her "life, liberty, and security of the person." Sheilah Martin reviews the three majority judgments and focuses on the decision written by Madame Justice Wilson. She believes that Madame Justice Wilson's opinion merits special attention in several regards: her conclusions on the constitutional rights of pregnant women; her recognition and validation of women's perspectives on abortion; and her approach to balancing women's interests in reproductive self-determination against the state's interest in regulating reproduction. Sheilah Martin concludes that this decision will reverberate far into the future. Even though it fails to establish clear guidelines concerning governmental power to control access to abortion, its principles outline the legal framework in which future litigation will occur, and it will limit and shape the terms of any ensuing political debate. In addition, Madame Justice Wilson's judgment holds great promise for those looking to the Court to promote the rights of women and other historically disadvantaged groups.  相似文献

Death notification--informing the deceased's family of an unexpected death--is a singularly stressful task common to medical personnel, clergy, and police. We surveyed by questionnaire a group of 50 Los Angeles Police Department homicide detectives, 21 of whom were subsequently interviewed by telephone. The detectives stated that their initial apprehension stemmed from feeling unprepared. Identification with victims' families was common and compounded the stress. One prevalent worry concerned the possible reactions of the family upon hearing the news, especially the risk of a violent attack on the police officer. Several coping styles were recognized. Our findings suggest that the repetitive performance of this continuously stressful task may be a prominent and underappreciated contribution to occupational burnout.  相似文献
