It's not stupid to believe the reporting from professional journalists. There's no way this guy was at a Children's hospital for more than 5 minutes before someone realized what was going on. This was just irresponsible reporting all around. These two threads were all based on MSM reporting from local and national news sources. If you can't believe that, what can you believe?
If this guy refused to provide his fingerprints as reported then LE knew as soon as that happened that this likely was not Timmothy. I think they should have said "we have no reason to believe... but we are investigating..." and poured cold water on this in the beginning. If it ended up being Timmothy, they would have good news to report to the world.
Any hint to MSM that this seemed to be a disturbed adult and not a child may have made the media tap the breaks.
