Anybody know if there's any comparable data from any other city? Police-involved shootings going back to 1970? Asking for a friend. 
I really was just asking for a friend. I'd like to know. Hard but not impossible to imagine NYPD is the only department that kept this data back then.
Here is the broader historical picture in NYC. ("UMOS" basically mean cop.) Two trends going on at once, one is reflective of the rise and fall of violence in the city, the other is a simple downward trend.
It's hard to imagine there were years in which the NYPD was involved in 2 shooting incidents each and every day. www1.nyc.gov/site/nypd/stat…
In 2018 NYPD had 17 "adversarial incidents" (shooting at somebody), the lowest number ever. Cops shot & killed 10 and shot & wounded 5 more. In 2016 there were 37 incidents. In 2009, 47. Back in 1971, there were 810(!) shooting incidents. In 1971 NYPD shot 314 people, killing 93.
