You're calling me daft yet you couldn't be bothered to answer the question. What is going the be legalized, as the above commenter wrote? What law is Flock breaking presently?
Like it or not recording and photographing people in public, then selling that information is not illegal. Paparazzi do it all the time. You can point a webcam out your window, run ALPR software on the video feed, and sell access to query that information. Nothing about that is illegal. If it is, then please reference the laws that prohibit this.
People talk about privacy laws being violated, but in general privacy laws do not cover public activity. Privacy laws mostly focus on protecting communications and activities carried out in private.
