From the sounds of this presser they aren't sure he is armed.
That would be odd. How's he pulling off these carjackings?
they don't have an idea where he is, apparently
Betcha LE knows if he took the weapons from the judge or others that he shot. They also would know the round expelled and how many remain most likely.
But PC would dictate LE hiding that knowledge from the public - we can't have more citizens carrying or using their own weapons in public. Paint the picture that he's unarmed to cut down on the armed citixen factor. Geesh.
