Taught not to get abused? I think you mean “stranger danger” shit, which is taught but the way you phrased that is disturbing. It’s not a child’s job to “not get abused by ‘anyone’”. And all places in general should probably keep an eye on who comes in and out, except for niche/specialized services like vpns, warez, etc. That’s just called being responsible.
Parks and other ‘loose’ non-stores though shouldn’t be held responsible, I agree.
