Greta says she's certain that something that was said during her interview led to the arrest.
Hope Greta doesn't hurt her arm patting herself on the back.
Greta is sharp, one of the best interviewers on TV.
As we only saw about 10 minutes of Greta's 45 minutes of taped interview... I am going to speculate PVdS slipped up in the footage we have yet to see.
Greta is a more than capable attorney. I'll bet she nailed him with more questions like: "Do you believe that he can go through this interrogation?" What a cleverly disguised, how-often-do-you-beat-your-wife question. She's good... damn good.
