That is fucking insane. I'm also separately sorry your friends are being stalked. I'd like to give a perspective here without sounding holy. Yes we have ANPR (what you'd call ALPR). There are national police databases and I am sure the cameras are very effective, but every search would require a justification of proportionality and access is not sold to the highest bidders. I think the furthest stretch of users would be the tax authorities' investigations departments. That a private company can profile citizens' movements like this is insane.
