Watch the movie . Between 3 minutes 20 and 3 minutes 25 into the movie Lewin draws electric current travelling across the surface of the capacitor plate.
According to Heaviside and everyone who followed him, Maxwell invented displacement current because the electric current, or charge, entering the capacitor immediately yearned to jump across the space between the capacitor plates.
For 150 years nobody noticed that the electric current entering the capacitor first had to spread out across the plate, as drawn by Lewin. When approached, Lewin refuses to discuss this sideways current, although it is said on the www that he always answers emails.
This sideways electric current undermines the story about the origin of displacement current, and also the justification for the invention of displacement current.
