Most criminals are dumb, some of them not only carry their phones with them, they even post their crimes on social media. With that and Flock I would think police work has never been easier.
It also depends on what you consider to be “criminal.” I’d wager most shoplifters are dumb. Most supervisors who engage in wage theft aren’t dumb. But that’s not the kind of person who comes to mind when we think “criminal.”
They also use flock to find and accuse people who did commit crimes and accuse them of having done so.
They also find and accuse people of crimes they didn’t commit without using Flock.
They also use Flock to skip accusing people who they might have suspected if it weren’t for Flock evidence that exonerates them.
It seems like any meaningful analysis needs to consider the rates of all four combinations of {true|false} {accusations|exonerations}, and compare that matrix to the matrix for the status quo techniques.
