Littlemisspiggy likes old geezers reply best because it is saying what she wants to hear.
It is the drivers responsibility to ensure passengers are belted when the car is in motion. My six year olds would NEVER take their seat belts off untill we say they can. Even now at the age of 9yrs they wait to be given the instruction.
Littlemisspiggy, You are responsible for your childs safety. It doesn't matter if she had only just taken it off or had not bothered with it at all. If you had had cause to slam your breaks on it that few seconds or someone had run into the back of you your child could be dead right now.
Your daughters 'hysterics' at being left in the car alone is your fault so stop trying to blame the police because it doesn't matter how long she was beltless they were just doing their job. Something perhaps you should take more seriously!!
Stop trying to make excuses and ensure you make the safety of your passengers ie: your child
