"I really thought that the defense would have more arrows in their quiver — but I would imagine they had trouble finding credible fact and expert witnesses given the nature of the case," he said. It was a conclusion drawn by several legal experts who provided observations about the performance of the prosecution and defense, both of which have now rested their cases after nearly three weeks of witness testimony in the closely watched case. "The defense was actually weaker than I thought," said David Schultz, a visiting law professor at the University of Minnesota. "I was expecting more witnesses, more medical testimony." Schultz said he suspects other witnesses defense attorney Eric Nelson sought out were unwilling to testify because they were concerned they'd be perceived as being "on the wrong side of history."
