"How fucked up people are" are not that much really. The odds of something happening to a 6 year old kid on their own in their neighborhood with an older sibling (and probably other kids & parents at a park around too) is extremely slight. People buy way too much into the fear mongering news stories. Something like 95% of child abductions are done by someone known to child and like half of those are by a parent during custody battles, etc.
