Civic honesty around the globe

1. The author failed to address to the special local practice in many countries such as India and China. I had experience in China that some of my friends put the lost and found information on their WeChat moments (something like 'timeline' in Facebook or moments in Path) . Others just hand it to nearby security guard hub, since the owner would ask the security guard anyway. These are common practice. As to email, it's a rare choice, even if we have it, we are reluctant to use it. For one thing, the general public doesn't use it anymore. For another, the owner would rather search along the way than check their dust-laden email box.

2. The survaillance camera coverage could be a fairly important factor, which is merely slightly memtioned in this article. Take China, UK and the U.S. as examples. China has more and more coverage of surveillance cameras now, about 10 per thousand person (http://new.mbu.cn/zjc/article/212/13759), but still not comparable to developed countries (75 in England and 96 in the U.S. per thousand person). This would change people's awareness whether there exist a camera or not.

3. As a scientific article, shouldn't it be culturally-neutral to avoid being used as tools to undermine some cultures? In this sense, the author and the journal editor clearly did not qualify. The result is potentially prejudiced and not purely scientific. And that's why lot's of people in these countries would have emotional comments on this.
