Do you remember the Toronto van-on-the-sdewalk killer? Do you remember his arrest? The police officer was brandishing his pistol, and demanding that the killer comply with his commands, but the killer was undeterred. It was only when the police officer has the idea to holster his pistol and draw his baton (instead) that the killer complied. And I mean the killer complied immediately... once he saw the baton... he'd been willing to be shot with real lead bullets, but he was unwilling to be struck with a real steel baton.
So you never know.
