The fact that 659,880 vehicles were stolen last year doesn't automatically lead to a suspension of personal privacy and the granting of authority to police officers beyond what they appear to be able to responsibly wield. I don't accept hand waving past the lack of oversight, transparency, and consequences to those who abuse their authority in the hopes that some meaningful portion of the 659,880 vehicle thefts are closed or reduced in future years.
It was 850,708 in 2024. That 23% drop had little to do with Flock, and is mainly the Kia/Hyundai software fixes, post-pandemic crime continuing to trending down, and focused programs in some communities around reminding people to lock their vehicles, hide valuables, etc. (you may have seen these signs in your area or the PSAs). Supporters of Flock and other camera systems tends to claim around a 10% decrease in crime for local communities that install their cameras, while the above shows that some thefts are dropping beyond that percentage regardless if cameras were installed.
