In real life, someone's responses to a traumatic event like loosing a child in a mass murder is not what movies and TV show. People will going on a out of control emotional roller coaster due to the shock of what happened.
People will act weird during and after traumatic events where they are completely powerless. Hollywood has conditioned people to think that everyone will just sit down and cry or go into police/military first aid mode. That is far from reality.
Jones didn't see what he wanted to see, the news didn't show what he wanted them to show, so he started making assumptions and accusations he could not back up. Calling a parent of a murdered children "crisis actors" went way too far and he was going to get the hell sued out of himself for it.
Did you see the aerial video of the crowd? You see the same line of people walking through a door to the outside, circling the building, walking back in, and then exiting the same way to walk around the building again. At ground level — for the benefit of a news camera, for example — it would look like your usual milling about after some disaster or other. But the aerial view is exceedingly weird.
