Put the hands up & keep em there.
That is the EXACT response advised by Tom Grisham on his radio show “Gun Talk”.
Put your hands up above your head and keep them there until the cops cool down and recognize that you are not a threat. Don’t surrender your rights, but at the same time don’t give them ANY indication that you are reaching for a weapon.
While your hands are above your head and they quit shouting sometimes conflicting orders, wait until they have quieted and then explain that yes you are armed and have the legal right to do so via CCW or in some states, state citizenship.
Never, ever reach below your shoulders until the situation is defused and calmer heads prevail.
