... runners had been crossing the finish line THREE HOURS before the two bombs went off.
Here is a video of the WINNER of the Boston Marathon (crosses the finish line around 4:10 of the video).
NO YELLOW BALLOONS.
So, they waited 3 hours for some people at the tail end of the race to put up balloons?
Yeah, suuure ...
Got nothing to do with the woman who's face is BLURRED out as she carries 3 yellow balloons, walking in front of the TWO BOMBERS.
