Having just read the story too it’s obviously appalling, if true. I hope, and expect, a thorough independent investigation is undertaken to discover the facts and, if true, that anyone involved, whether directly or indirectly, is given the appropriate punishment. Which would be severe given the abuse of trust involved.
I hope it was just one officer, or a small number, of rogue officers, acting alone. Unfortunately corrupt officers do exist. Doubtless this will attract a lot of attention but until we know the truth, and the scale if true, I hope, but don’t expect, that there won’t be any rushing to conclusions. The most important thing right now is to ensure the investigation is trusted by everyone so there cannot be any suggestions of cover up.
