I'm not sure I buy that, only for the reason that I don't think most journalists are paying enough attention to connect the dots: "this happened on Mubarak's watch, but don't we send him money? So we probably shouldn't talk about this." In my time as a journalist I never saw anyone who cared about that connection - now they may have cared about something that directly impacted "their guy", and if the guy thought there would be something directly implicating a favorite specific politician, then I would buy it.
Journalists in general (just like people in general) have limited vision - a lot of times not by choice, just because they have a finite amount of time and a finite amount of energy to spend on certain issues. They are invariably going to go after things that are right there in front of them, as well as things that they see as being a public "hot button".
Two years ago, no one really cared what was happening in Egypt - it just wasn't on the radar. Now it's a hot topic, people are paying attention, so when you're a copy editor and selecting stories to run, all of a sudden Egypt looks more interesting. from a coverage standpoint, I would imagine there are a lot more journalists there now covering things, so there's more opportunity to look into this stuff.
You may be right, but I just think you're giving journalists too much credit in being far-thinking.
