“Scott does the very best thing possible - removes the whole holster so he can drop the gun without unholstering it.”
Do you really think that was the best thing possible? Moving your hands to within inches of the gun?
What he should have done is exactly what someone else said: Put up his hands. Up over his head, or clasped behind his head. It’s all about the hands.
No sudden moves. No unnecessary moves. No moves that might be misinterpreted.
Attempting to drop the holster sounds very much like what someone on drugs would do.
