I wouldn't exactly call the reporter "calm" during that...
She was calmer than most people would have been. There are probably many reporters who would have cut the woman off after 4 minutes, or threaten to bludgeon her family to death. All and all, the reporter did keep some level of calmness throughout the confrontation, even if it wasn't the greatest. :o
But than, you could say the same in a situation where: "Well he killed 10 people - but at least he's not Riddler!". :s
