I am working on a research project with Dr. Jurgen Brauer (www.smallarmsanalytics.com) to estimate the quantity and value of ammunition produced and imported / purchased in the US annually, in particular from state and municipal police forces. I see that there is high-level information on police spending in the 2018 Comprehensive Annual Financial Report, but I am looking for a more detailed breakdown of police spending. The particular data points we are interested in are the total values and quantities of ammunition per year, for as many years back as might be available. We'd ideally like to be able to calculate the value per round or cartridge.
Please let me know if you can assist me with this research project.
