Why French Police Say Parents Shouldn't Put Kids' Photos On Facebook

One of my concerns having posted photos of our kids on RP, Twitter & Facebook. But I don't list their names or addresses...Any thoughts from parents and/or grand parents. I'm not comfortable with Facebook but thought posting my two little rascals here would be ok I have also swapped photos and stories with other parents and grand parents...I started a discussion about bragging about out kids and sharing photos.

But not sure if that was dumb or not..I know their mother doesn't like it and doesn't want me trying to get my grand son to be a Marine when he gets older.
