you could let your kid run free & unsupervised with little worry on probably near 90+ percent of the north american landmass. i spent the vast majority of my childhood with little to no supervision and crime rates have only fallen since then.
You spent your childhood in a time before helicopter parenting became legally mandated. If you let your kid run free and unsupervised today in America, you will probably end up with a visit from CPS and/or the police, and you might get arrested. It has nothing at all to do with crime rates.
