Editor's note: The question over whether photo-taking should be allowed on the subway arose when the Beijing Metro launched an online survey on its official Sina Weibo account. The survey shows 75 percent support taking photos on the subway. What do you think? You're welcome to leave your comments.

So far any laws against photography on subways in UK have been limited to not being allowed to use your flash because it may distract train drivers - other than that, taking photos is fine. At least it has from my experiences in London, anyway. I've never once been asked to stop taking photos.
