Considering the background of the country, this is to be quite expected. To the people, Muhammad is a very symbolic and religious symbol and for someone to joke about his image on facebook is taboo. The image of Muhammad is scared and is not supposed to be depicted in anyway. Its very insulting to this culture.

Do not get me wrong. This is a bit extreme and I wouldn't approve of it, but I do not live in Pakistan and their political and governmental structure is far different from our own. A lot of people probably support this kind of punishment, while some probably don't.
