Counts are the organization's own, as filed with each agency. Most state portals count their own residents only, so no single state shows the whole incident. An organization can file more than once for the same incident, and for different ones.

The next state to file on Middlesex Sheriff's Office reaches subscribers within the hour. With the count, the data exposed and the letter. The Team plan follows the companies and vendors you name in every state. Start a 14-day free trial.
