My comment:
(a) It is shocking to discover that the first half of the BBC report is a plagiarism, copied and pasted from
刘欢, 香港警方还原内地幼童小便事件经过：2岁幼童是男孩. 新华网山东频道, Apr 23, 2014. www.sd.xinhuanet.com/news/2014-04/23/c_1110378857.htm
(i) So far, the only follow-up is from Xinhua, which published this report only. All other news media cite this report, with attribution ("新华"); only BBC Chinese does not mention the source (VOAhas not reported on this).
(ii) It is hard to believe 香港警务处公共关系科当值新闻主任 gave an interview with Xinhua only (because it is conceivable news outlets would like to ask Hong Kong Police Force 香港警务处 questions), but this is the case.
It is 11:30 am EDT, Apr 23, 2014. As of now, 环球时报has deleted this commentary. Maybe for good reasons: It talked about 女孩, disclamer notwithstanding ("由于这一冲突的细节未得到视频的完整复原，我们认为，媒体对这件事的评论不应以网上传闻为基础，从价值观出发勾勒现场未必真实的画面"). Never says a word when fact is murky.
