I have also heard a lawyer on the radio explain that LEGALLY once you make physical contact with someone carrying a gun you are BOTH considered to be ‘in possession’ of the firearm and so he was NOT UNARMED.
I believe the officer that he tried to take his gun and would have done it again.
Gunshot evidence inside the vehicle will be another damning piece of evidence.
But Hey! ...who needs evidence when there's an opportunity to riot, burn & steal stuff.
