First my point was that the call was probably triggered by more than just messy hair and ill fitting clothes. That the person who called may very well have mistaken behavior typical to Autism for signs that the child could be suffering for neglect or abuse. I would rather have someone err on the side of caution. Especially when there have been recent cases in the news where somebody should have taken the time to call.
Some have written the person who called should have talked to the parents. But approaching a stranger to ask rather personal questions about the condition of their child can be at the best awkward and at worst dangerous.
The cops did not go in making accusations against the parents. They told them the situation and observed that everything was fine. It is better they were called then CPS. Since CPS sometimes as an attitude of all abuse all the time.
The cops did a good job, that I will agree.
