This is a perfect example of how fragile important things can be. If there was some valuable unsaved information on a computer before it was reset than it could have been forgotten about in the wake of new information. Also, if reports came out about a station's computers all resetting at once then Alex Jones and other conspiracy nuts would have a field day claiming that it was an inside job.
In that same vein, the Boston Bomber internet witch hunt contained tons of extra information which was not pertinent, but it was still heavily scrutinized by the conspiracy crowd. How many of those tidbits of information were the results of overhearing a different case on a police scanner or a misunderstanding? Cable News stations seem to have gone the way of reporting any and all information rather than ensuring that the information is both credible and relevant.
News media needs to stop and count to ten as well as news consumers who were ready to start pointing barrels after the first reports of MH17 going down.
