This happens everywhere, it doesn't have to do with race. I have a family member who has children in very posh and upscale neighborhood in a suburban area of NoVa. She has had neighbors call child welfare several times for her 10 year old skateboarding around town, or playing at a playground unattended with friends (literally a block away from their home). I get the vibe that alot of older residents don't want children running around because they value peace and quiet, so they call the cops/DCF when they see kids hanging w/o adults.
