I watched the interview with Officer Wilson, and one thing really strikes out to me. Wilson states that when Brown grabbed his handgun, and Wilson tried to pull the trigger, it would not fire because Brown had his hand on top of the gun. That obviously makes zero sense. The only thing I can think of is that the gun may have been a double action, and brown had his hand on the hammer, and this prevented it from cocking back and firing.
Here is a link to the interview. What do you all think?

Perhaps with Browns hand on the top of the gun, it was pulled slightly out of battery?
