I sometimes wonder about whether the police can spot anything.A few years ago I was in a shop,waiting at the till behind a woman who had a full basket and a little girl of about 5.A few minutes later the woman noticed that the little girl was outside the shop,moving away quickly,and ran out to get her.While all this was happening three policemen were standing at the door of the shop talking to the manager.The little girl would have had to squeeze past them to get out of the door,and not one of them noticed.
I challenged them about it and they weren't bothered,in fact one of them was quite abusive to me.
