During the 1980s , the police department was at the center of a case that came before the Supreme Court of the United States and Ninth Circuit , '' Kolender v. Lawson , '' 461 U.S. 352 ( 1983 ) , which held unconstitutional laws that allow police to demand that " loiterers " and " wanderers " provide identification ; this continues to affect other departments nationwide . The decade also saw officers responding to the San Ysidro McDonald 's massacre ; it was also a decade where the department had the highest mortality rate for officers of any major American city
