There is some merit to that instruction, ASSUMING you have the liesure to give the command. Just as we SHOULD ID ourselves before shooting, assuming that doing so would not jeopardize us or someone else.
Another thing that is a good practice is to say "quit resisting" or "get down on the ground" repeatedly as you are striking someone. It accoomplishes 2 things: the witness around the corner can say, "I heard the officer telling him to quit resisting..." and it also pounds the command into the idiot bandit as you reinforce it with physical assistance.
We bring evil things to evil people, kicking in a door near you!

an eggs-and-ham breakfast: the chicken was 'involved' - the pig
was'committed'."
