First of all, you have to realize where the problem comes from.
Actually, social media or citizen journalism of all kinds is a fantastic new resource for reporters and journalists around the world to get a view of current events in distant places. These types of initiatives by governments that you're describing are designed to shut that down, are designed to stop the sources of information that are now becoming available that were never available before. It was very easy to stop people leaving the country or newspapers leaving the country. It's very hard to stop video from spreading through the Internet, video that is, of course, high-quality, fact....
The difficulty that journalists face, and which still requires a lot of discipline on their part, is to separate what's real video, genuinely taken and unedited, untampered with, from the vast amounts of false information that governments and others are generating and circulating on the Internet.
There's still a challenge. Part of it is a technological challenge. However, that's what good journalism is about. There's actually an opportunity here. The reactions of governments such as the one you've mentioned have to be seen in that context.
