Put your hands up. Listen and obey. Get down on the ground. Listen and obey. Step out of the car. Listen and obey. Is a direct command really hard to follow?
Ask questions? Only when required. While there's no logical acceptance for them to be. When you are aware that the one you asking might not give you an answer.
Speak only when spoken too. Listen and obey. For speaking out of term will open you up to this, "who's talking to you?' Listen and obey has it purpose.
