If a LEO wants to disarm me during the stop, it's his call.
But I would rather he didn't for two reasons:
1) anytime you handle a gun you risk an accident. I'm not afraid to unholster and unload in the car; I do it frequently. But under the stress of a stop, the risk goes up slightly. Not a big deal but why risk it?
2) my main point of confusion is when as cited above, the officer is worried about my frame of mind. If I am a bad guy or a wacko and the officer asks me to unload, isn't he giving me a huge advantage over him since he has just agreed to stand by and watch as I unholster my gun? Wouldn't that definitely put him behind my OODA loop?
Maybe one of the LEO's on the forum can point out the flaw in my thinking.
