Getting arrested in the US is never as straight forward as "putting your hands behind your head". According to a popular US police reality show called "Cops", cops always use many different conflicting instructions. Sometimes they want you to put your hands up, sometimes they want you to interlock your fingers, sometimes they want you to face away from them, sometimes they want you to get on your knees, sometimes they want you to get on your stomach, sometimes they want you to stay in the car sometimes they want you to get out, sometimes they want you to take 3 steps backwards, sometimes they want you to take 4 steps to the side, sometimes they want 4 steps backwards and 2 steps to the side. Heck I've seen many episodes of Cops where one officer is yelling one thing and another is yelling the complete opposite instruction.
Yes as a deaf man you should know that you need to yield to an officers demands, especially one who's pointing a gun at you, but then how is the deaf person supposed to know if the officer wants him on his knees or if he wants him to take 3 steps backwards and get on his arse and is not hearing an instruction such as "interlock your fingers" enough reason to get floored?
I mean there are so many verbal instructions officers use when arresting someone at gunpoint (just watch an episode of Cops), and you need to do it in the correct order without any deviation. I don't see how it's possible for a deaf man to get handcuffed at gunpoint using the same procedure a hearing person would.
