In addition, there are (almost) no restrictions on private entities capturing and storing such information (such as casinos, stadiums, amusement parks, concert venues, etc). In a similar way, many police departments completely circumvent the restrictions on them keeping license plate reader data by simply purchasing the data from private license plate reading companies. They just submit a license plate number and receive a comprehensive report of when and where the vehicle has been photographed for the last 12 months or longer. Repo companies and private dicks are other major customers of this segment of this data market.
