We started hoping that car thefts would be a pressure point for a lot of violent crime (which tends to be committed from stolen cars --- this is the Kia problem). But we caught more innocent drivers with stale entries on the Illinois LEADS hotlist than actual stolen cars. When we OK'd the system after its pilot, it was on the condition that we no longer curb cars based on stolen car reports at all --- we'd only curb them based on stolen license plates (which have no innocent explanation).

Maybe other states are different for this, but in Chicagoland, unless you don't care about disproportionately harming Black motorists, using Flock for stolen car enforcement was a flop.
