Drama between President Obama and His wife Mitchel

UK Prime Minister David Cameron, US President Barack Obama and Danish Prime Minister Helle Thorning-Schmid have faced serious backlash from people since these photos of them taking a selfie at Nelson Mandela's memorial service in Johannesburg was released yesterday.

People online are accusing them of undermining the seriousness of the event by smiling and taking photos on their mobile phones. I don't know what these people are talking about, I think it's adorable and shows they are regular people like us, at the end of the day. What do you think, was this inappropriate?
