She was apparently willing to testify for the sweet Jodi she knew, but according to JM refused to answer questions about her drug use and took the fifth re: her sale of pics. IIRC there were problems with her attire and sobriety on the day she was questioned - some pundits hinted that was the reason court was held up - and JM actually stated "It is clear she has some kind of substance abuse problem" that would have been addressed if she testified. She can go on Dr. Drew or HLN and claim she's never had a problem, but if that's true, why couldn't she testify to that under oath?
If she has done nothing wrong, there was no need to fear being questioned by JM and little need for Nurmi and Wilmott to offer her legal advice re: taking the fifth. She can talk all she wants about being bullied, but there have been people that have testified in order to put away organized crime types, drug kingpins and vicious gang members - now those people seriously had reason to fear, but her tales of fond memories of a teen friend?
She was even offered a chance to testify off camera, so why all of a sudden worry about internet gossip now? Especially since she was so willing to put herself out there in all her glory prior to the trial, and people have been talking about her since her first interview. She was more than willing to show up sitting next to the mother, either drifting off or giggling in court when she knew she would be on camera. Her claim of threats as the reason for her refusal gave the DT one more opportunity to ask for a mistrial and attack JM for 'bullying'. I tend to doubt the DT had any intentions of allowing either DB or Patti to testify, but they used her refusal and she is going along with it now.
I don't read those FB pages, but from what I have seen of her myself and what was said in court, I have little to no sympathy for her.
