This picture is obvious: reporters' sound technicians leveraging their microphones to pick up what U.S. President Donald John Trump might say, in the darkening twilight.
That is not, however, how I (BMcC[18-11-46-503]) initially saw it. I saw those little black vertical objects at the end of the long horizontal arms as: traffic signals, which were advising President Trump to stop ( Red), watch ( Yellow), or go ( Green).
Would that my mis-constellation of this picture had been correct! What a work of art! If the traffic lights were not synched to The Party Line, maybe they would be warning Mr. Trump to think before inserting his foot in his mouth and biting down on it, to borrow from a cliche, as he often does.
