Why couldn’t Harrison’s father, George, remember his son’s arrest?

In Kurt Vonnegut's popular short story, Harrison Bergeron is taken away by the government when he is 14 years old. The arrest of one's son should be an extremely traumatic and memorable event, right? One would think. However, that is just the problem. In the society in which the characters live, the goal is equality and intelligence is handicapped to ensure total fairness in all thoughts.
George Bergeron, Harrison's father, simply cannot remember his son's arrest. George is above average in his intelligence, so he has a radio implanted into his ear. The piercing sound of sirens, loud and boisterous crashes, and discordant booms litter his ear canal, hindering his thoughts.
So here is George. His thoughts are not consumed by the worry of his son's arrest. His thoughts are muffled and his physically abilities limited by the handicaps he is forced to wear. George is an apathetic character. The weights and sounds and limitations of his life have subjected him to a listless existence, one that is void of care or want and any desire other than a nice spot in front of the television.
George is submitted. George, well, George simply does not care. He has been beaten by the literal and figurative weight of his government. His son has been arrested, but the "why" does not even register.
