OFFICIAL POLICE BUSINESS is an occasional email newsletter that collects the most interesting data and journalism about the companies selling technology and weapons to cops — and the machinations police officials go through to squeeze those products into policing budgets. Think Tasers, predictive policing, and facial recognition; body cameras, StingRays, and automatic license plate readers. OPB is compiled by journalist Matt Stroud (@MattStroud).
