So we're back to what I said earlier, we only disagree about what is common or rather 'not that uncommon', which is the phrase I used.
We can be used to things that happen much less frequently than one a week, for example I would call major political scandals relatively common, and hence relatively unshocking, and they are much nearer the 3-4 a year mark than one a week. In general terms, if something happens reliably once a week it's probably not that newsworthy. The photo is probably unique, I've never seen anything exactly like it, but photos of that type are not that uncommon.
Anyway, we are back to where we were several hours ago, we're going round in circles on minor definition issues so I'm done here.
