Dr. Loftus is not one of your usual "just make some stuff up" psychologists. Her expertise is experimental, not clinical, and she may well be America's leading expert on the reliability of memory in eye-witness testimony.
If she is disqualified as an expert, that might be grounds for an appeal in the event of a contrary verdict.
Loftus is at the top of her field.
She has been instrumental in some of the reversals of the demonic daycare abuse cases made from coached memories from kids 15 years after the supposed abuse.
