I think someone that worked with Law Enforcement for so long has an established credibility.
I used to watch her on the days she was on Montel.
The people in the audience appeared for real; not staged as she would discuss their issues...just watch their eyes...the eyes don't lie.
I loved when she made her yearly predictions and would write them down. She was pretty bang on every year.
I have read most of her books and she has a clarity to her words that few people can convey.
John Edwards appears a bit to staged to me but that is just my opinion.
