Claims about police shootings

There is a new book by Tom S. Clark, Adam N. Glynn, and Michael Leo Owens, called Deadly Force: Police Shootings in Urban America.  Here are a few of the conclusions:

…we were more likely to obtain records [on police shootings] from cities with women mayors and more women on municipal legislatures.

And, most interesting to me:

…we also found that fewer police shootings occurred in cities with more police, all else equal.

And:

…Black and Hispanic officers are disproportionately the ones involved in police shootings.  That is particularly true when a Black civilian is the subject of the shooting.

I do not follow this area closely, but the book seems of interest.
