Final answer:

Step-by-step explanation:
From 1985 to 1990, the exact number of deaths resulting from gang warfare according to the LA Sheriff's department is not provided in the reference material available. However, it is important to note that the period was marked by significant gang activity and related violence. The 1980s saw an escalation in the war on drugs, which contributed to a rise in incarceration as well as violence, including gang warfare. The years following saw efforts to reduce such violence and improve policing methods.
For context, it is mentioned that the period from 1970 to 1980 saw police deaths averaging 231 per year. A significant reduction in violence and fatalities among law enforcement personnel is highlighted, with a dramatic decrease in the number of police officers killed in the line of duty over the subsequent decades. While specific figures for gang-related fatalities in that time frame are not specified, the overall trend in later years shows a decrease in gun homicides and an increase in safety for law enforcement, indicative of efforts to curb such violence. It is crucial to look at historical data, social context, and trend analysis to gain insight into gang warfare and its impacts.
