Did Zimmerman told his friend betrayed bond Marten granted his gun rather than Zimmerman just -- Marten was about to reach for it as he told police. -- you recall he even told you to achieve -- monetize the -- you -- you reaching for. I thought he said he had grabbed. The gun. I've only heard the story twice what it was. Grabbed -- gun rack for the practice. Perhaps it was just intact.
