They can’t have it both ways:
it takes a picture of a car. Most people go, “this makes a lot of sense. I want my kids to be safe.”
If it’s just taking pictures of cars, it’s doing nothing to keep kids safe. I take pictures of cars. Does that somehow make kids safe?
However, if the argument is: “the system knows where all cars in the area are and have been, and so can keep kids safe…” well, that STILL doesn’t keep kids safe, just allows some understanding of what caused the problem after the fact. But it also lets those with access track where every vehicle is. And then tie in the OTHER cameras the system has access to, and you’re no longer tracking cars, you’re tracking people (and dogs, apparently).
