It gets worse and worse in each successive case. Often, it seems like news agencies take something from the wire and start to assume things and extrapolate information; then other news agencies go from there, and so on. Or, on the other hand, they all just take something straight off the wire and don't look into it at all, so you've got 1,000 stories, but they're all exactly the same.
Doesn't the news media look into anything anymore? Why don't they fact check? Dig deeper? Find new sources? Do some research?
