This is what has been happening on cable news for the past few hours: After insisting that they had confirmation from two separate sources that an arrest had been made in the marathon bombing, and while ignoring reports from nearly every other source that said otherwise, CNN was forced to admit that there were then three sources telling them that no arrest had been made and just recently changed their report status to "conflicted." Meanwhile, there were several different descriptions of the "suspect" that was never identified in the first place in is not at all in custody but might be for all we know.
