I can't believe this has not been done prior to now. I'll bet most other countries are way ahead of us in this area. You will never get a clear picture of what is going on, and where until data is collected state by state, city by city. It would make it easier to weed out bad cops who move around, knowing their record won't follow them. This kind of database would be easy to design and implement. If I were younger, I'd volunteer to do it myself!
