Are you seriously unable to work it out yourself? I thought you were bright. Obviously I was mistaken, so here is my question again, written grammatically correctly to enable you (hopefully) to fully comprehend it:
“In your opinion then have all children who go missing not been properly protected by their parents?”
I misplaced one word in the original and you made a pedantic issue of it. Utterly pathetic IMO.
I'm bright enough to recognise a question when I see one. The answer is no, imo not all children who go missing have not been properly protected by their parents. I was referring to one case and for some reason you chose to suggest I was referring to every case of missing children.
Obviously I don't know the circumstances surrounding every case involving a missing child. I do know that some are never returned to a parent's custody, being kept away by their other parent, so the parent with custody isn't to blame. Other children run away, which makes it difficult for parents to prevent. So all cases are different, as I'm sure you know if you think about it.
"Misplacing" a word can change the meaning of a sentence.
