Sounds like the DR trying to testify for GZ to me........I would understand his describing what happened, but saying he is authorized to carry a weapon...and calling TM the "attacker" IDK.....smells funny to me.
Strange to me too but then again I'm not sure if that's standard or not. Looks like he may have asked how he came about his injuries so he was just putting down what GZ told him verbatim.
