"No more gaps – just evidence.
A license plate is just a start. Flock’s Vehicle Fingerprint® tech turns footage into evidence that solves cases by pinpointing vehicles by make, color, type, and unique characteristics like decals, bumper stickers, and accessories. This capability proved to be instrumental in a recent case in Catoosa, OK where police were able to track down the suspect connected to a mass murder after their vehicle was spotted by a Flock camera."

So we need color changing cars and we need to make changes to stickers, wheels, and accessories more frequently. It will be like the characters in cyberpunk novels with the odd face paint and stickers that they can change so as to frustrate facial recognition.
