More than 500 arrests for leaving children unsupervised is one of those dichotomous questions that brings heat to debate, but without context or detail can offer little use to parents, especially those who may be struggling with multiple child care and economic demands. Smoking debates are pretty much over now, but we can usually still find someone whose grandfather smoked 50 a day for 60 years and it never did him any harm. There will always be an exception. On the other hand there will be ludicrous examples where the letter rather than the spirit of the law has been applied to make a mockery of common sense underpinnings about leaving children unsupervised. We understand that getting a speeding fine 5mph over the limit on empty road at four am might be irritating, but it is protecting the local school children later in the day. With a population of over 64 million, where it is likely thousands of parents have left their children unsupervised at times, 510 arrests seems very few. What it does not tell us is how many were released immediately after caution, how many were serial and repeat offenders, how many posed a serious harm to their child with their arrest pre-empted another tragedy.
