The alleged victim is taking the stand as the very first witness. This case has rocked the top college program and divided a community. "Gma's" legal analyst, dan abrams, is here. There's accusations the college hasn't been good on handling these allegations in the past. Inside the courtroom, it's a high-profile he said/she said, playing out in montana this week. With the alleged victim and the accused facing off in court for the first time. Her identity protected, she is the first witness called by the prosecution in a case that is bitterly divided the missoula, montana, community. The woman is accusing the former star quarterback, jordan johnson, of forcing her to have sex, after she invited him to her room. Taking the stand, she said how the two had flirted, even kissed.
