For U.S. readers, the title of this post may not seem quite right. You’ve heard of stops, based on either reasonable suspicion or probable cause, and frisks for weapons following a stop. You know about racial disparities in criminal justice data. But, what’s stop and account? Stop and search? And, how do they differ from stops and frisks? As I’m in London for the fall, the answer is pretty obvious that these terms refer to police authority in the UK. What may be less obvious is how this authority resembles the stopping powers of law enforcement officers in the US.
