Until today I would have doubted it, but now I think he will.
Today we saw Feldman ask questions about the record of Girl Scout Cookie sales and make a statement regarding reciepts for tax deduction purposes.
BVD said there was no record and the subject was dropped. I think there is a record and that it's a cancelled check, dated later than the tuesday BVD swore that she was sure they were there selling the cookies. Why would this be important, other than yet another impeachment of BVD's testimony? Because it may have been after Danielle got her hair cut. Hmmm? That would certainly negate the hair "length" evidence.
Wild speculation, I know, but you can bet Feldman had a purpose for this line of questioning.
Oh, almost forgot! About your original question about DW taking the stand. If my theory is correct, DW would have to testify to the writing of the check.
