Enforcing the law becomes a lot harder when a community lacks trust in you, and kids who don't trust police officers turn into adults who don't trust police officers, and teach their children the same thing.
Bog-standard "if you get lost and separated from your parents" child-advice is to ask for help from exactly such figures as police, with the idea that this would protect them from ostensibly less savory options

> The best people to seek out would be the police, security guards, the fire department, and store management and employees. If these can’t be found, teach them to seek a mom with young children.

> Advise children that if they need assistance they should only approach someone such as a security guard, police officer or someone who is clearly a member of the staff.
I mean, I know these are just random internet things -- but I vaguely remember that advice even being in kids' books when I was growing up.
I remember receiving that advice as well, but would be less likely to perpetuate it given the frequency of weaponization of the State against parents. If I knew the community, I might advise the latter.
