Nobody knows it off the top of their head because the SDA verbiage conflicts with standing precedence (Terry etc...) that upholds an officer's discretion to disarm for officer safety during a detention. Which makes it a gray area free from absolutes.
It probably happens so infrequently that it's never bubbled to the surface.
As for WNM being jacked up with hands on the hood? Smart call there...he's a shady sumbitch. I'da had him at gunpoint.
You're talking being detained... is a simple traffic stop considered the same thing as being officially detained??? Just curious, really. I've never been "disarmed" but I've had the officers ask me to come back and sit in their car, which is fine by me. I don't usually carry on my person in the truck, it's in the door pocket or console, in the car it's under the seat. If I told them I was carrying on my body, maybe they'd handle it differently, I don't know. I don't get pulled over too much anymore, though... maybe 3-4 times a year.
