What the heck did he have to put her in a safe house for? I think I know, but it sure looks funny. She was in no danger from any of these boys or their family. Now the boys could be in danger from her "friends" but not her.
He put her in a safe house so he could watch her and make sure her life-style does not impact the case between now and the trial. As others have said, she is likely to tire of that sooner rather than later and well before a trial in Spring 2007.
She isn't in any danger from the Duke boys and their families however I do think she could be in danger. She probably knows a lot and could finger a lot of powerful interests in Durham.
Think about it, if you were running a lot of drugs and prostitution and who knows what else, would you want her to be on the stand under cross examination? It's good she is in protective custody. She *could* be in danger and if anything happened to her the boys would be blamed.
