That doesnt necessarily keep you safe.
If you are like me you have pictures on your computer. I rarely ever print pictures. My wife occasionally gets pictures printed at Sams Club. I always put the pictures she wants on a blank thumb drive for her to take along. If she had her way she would take the camera flash card. I tell her it easier to (and safer) look through the fotos at home than to stand in front of their machine and sort through the whole card for the pictures you want to print.
But to the point, those pictures on your computer are just as incriminating as those that this couple dropped off at Walmart. If for some reason you come under suspicion of a crime and your computer is taken as evidence those photos will be seen and you could be indicted for baby pictures.
I have pictures of my oldest grandson belly surfing in our bathtub. They are great pictures. But they have never been printed and except for my wife and I no one has ever seen them. Someday when he is older and engaged they will be brought out for viewing.
From this it would appear that the CPS employee without reviewing any of the evidence collected that day decided to take the children.
On only the evidence of the Walmart photos which had no frontal nudity the CPS worker decided to take the children and put them in foster homes.
Does it never occur to these people that it is traumatic for the children to be forcibly separated from their parents. As far as children that age is concerned they are being kidnapped. There is no difference.
This person and the supervisor should never work in social services again.
