If I saw a 10 and 6 year old walking down the street it would never occur to me to call the police. It wouldn't occur to me to call the police for a six year old, unless the kid appeared to be lost/distressed.
I can't remember if I walked to school when I was 6, but I know I did when I was 7. I also remember running around the neighborhood with my brother when we were 5 and 7 (actually I think it was 4 and 6 but I'm not quite sure). Probably "around the neighborhood" was a smaller zone than I remember, and probably my mother had more of an eye on me than I knew, but still.
