End of game delay warning

[CoachJW]

Team A scores to cut their deficit to 1 point. Time is at about 4 seconds when the ball goes through the net. The officials are going to correctly follow the casebook comment and let the clock run out anyway, so Coach of Team A calls for timeout. He'll take the T, the chances of Team B making the FTs, and try to steal the half-court throw-in.

Do you whistle to kill the clock, knowing that he will benefit from it?
