Was the halftime flash planned?
First: Watch what you print. Janet was no more wearing a pasty than Justin was. Any close-up shows that it's jewelry, a "nipple shield" held on by a barbell through a piercing. Was she wearing it because she knew her breast would show? I don't know. But the "pasty" is no evidence that it was planned.
Second: What about the "shocking moments" promised in an MTV.com story? Read in context (in a quote from her choreographer, Gil Duldulao), that doesn't sound so salacious:
"I don't think the Super Bowl has ever seen a performance like this," Duldulao added. "The dancing is great. She's more stylized, she's more feminine, she's more a woman as she dances this time around. There are some shocking moments in there too. It's a lot of pressure, there's so many creative people and creative artists, you want to make sure everything is different, and I think she's going to do that. She's doing her job well."MTV has taken down the story, but you can find it in Google's cache.
Sure, the event may have been planned. I don't know. But for newspapers — yes, even columnists — to cite the above reasons is sloppy reporting.
