A report on 1990 hate crimes in Los Angeles County (California) found 275 racially motivated hate crimes, 150 religiously motivated hate crimes, and 125 sexual orientation hate crimes. The data were collected primarily from law enforcement and community agencies. Of the racially motivated crimes, most were aimed at Blacks, followed by Asians. Jews remained the primary target of religiously motivated hate crimes, with Muslims and Catholics the next most numerous victims. A 45 percent increase in crimes against sexual orientation was documented with the overwhelming number of incidents aimed at gay men. Although graffiti vandalism was the most common expression of racial and religious bigotry, assault was the most common type of sexual orientation hate crime. Residences were the most frequent hate crime site in 1990. Also noted was a strong correlation between the Middle East conflict and increased acts of anti-Arab and anti-Muslim bigotry. The report also treats crimes against women, legislation and legal actions, non-criminal acts, a discussion of why hate crimes are rising, and what can be done to reduce their number and a list of Commission actions. Statistical data are presented in 3 bar graphs and 16 tables. Lists of the incidents divided into racial, religious, and sexual orientation categories and definitions of hate crimes are appended. (JB)
