Barack Obama secret service - is it even a story yet?

I know journalists must look to journalism before public service - that's their job. Tonight on the Chicago ABC, CBS and NBC stations, each 6 o'clock broadcast started out with the new Secret Service detail on Obama. The major point for all coverage was that there have been no threats against him but that this was the earliest a candidate has ever needed Secret Service protection. I guess I was shocked that this was hot enough to lead the newscasts here - yes, it was new and thus "news" but it wasn't really a story yet. The presidential race hasn't really begun and no specific threat has been released. It may have been news, but what was the point? There was some "watchdogging" involved, I suppose, because Obama has made no comment and the only video for the story was Obama walking with what looked like bodyguards with hearing aids. I had seen the story on the 5:30 network news for NBC and ABC, so maybe I was just informed enough already of something I didn't think was that newsworthy in the first place. But our stations leading off with something I didn't think was that much of a story - I was surprised. Wasn't there anything else going on? I couldn't tell you. After flipping through the top of each show looking for something different, I switched away from news altogether.
