Excerpt; There's actually been progress in the 30 big urban areas:

Police departments in America’s 30 largest cities killed 30 percent fewer people in 2019 than in 2013, the year before the Ferguson protests began, according to the Mapping Police Violence database. Similarly, The Washington Post’s database shows 17 percent fewer killings by these agencies in 2019 compared to 2015, the earliest year it tracks.

This data isn’t perfect. The databases have slightly different methodologies for collecting and including police killings. And not everyone who’s shot winds up dying, which means some people who are shot by police don’t end up in one of these tracking projects. So to better test and understand the progress made in these big cities, I compiled an expanded database of all fatal and nonfatal police shootings by these departments, which expands our view of any changes in police behavior. Based on data published on police departments’ websites and reported in local media databases, I found data covering police shootings in 2013-2019 for 23 of the 30 departments.2 An analysis of this data shows that police shootings in these departments dropped 37 percent from 2013 to 2019.
