I was a mere pup of nearly 14 years of age on Nov. 22, 1963.

I was home that day, nursing a bad cold. Mom and Dad had gone to work. My sisters were at school. I was watching TV when the news bulletin flashed on the screen: “Shots were fired at President Kennedy’s motorcade in Dallas, Texas; no word on whether the president was injured.”

The “word” came quickly. The president was rushed to a hospital. Doctors worked to save his life. They failed. Then came the announcement: “President Kennedy is dead.”

My first thought in the moment was clear and simple: The Soviet Union did it. Not only that, they were going to invade us immediately. The United States was without a president. We had no leadership.

Remember that I wasn’t yet 14. My mind ran wild.

I remember those initial thoughts today as Donald Trump has released many thousands of previously classified documents related to the Kennedy assassination. I’m hearing lots of talk that conspiracy theorists are going to run wild with this stuff. It’s going to substantiate their already-loony belief that someone other than Lee Harvey Oswald was involved. It was the Mob, the Cubans, the CIA, the FBI, LBJ, men from Mars, the Creature from the Black Lagoon.

I settled down over the years about what I truly believe happened that terrible day.

My 13-year-old concern about the Soviets was ill-founded, to state the obvious. I didn’t realize in the moment that Vice President Lyndon Johnson took the presidential oath of office in Dallas. He took command immediately. And the Big Bad Bear didn’t attack us.

I have grown up since then and have come to believe that Oswald did it. He acted alone. He snuck into the Book Depository Building. He waited for the president’s motorcade to pass under the sixth-floor window where he was perched. He squeezed off three rounds and fled. He got caught in the theater, shot the Dallas police officer and was arrested.

He wanted notoriety and, oh brother, he got it.

I also believe Jack Ruby wanted to be remembered, too, which fueled his desire to kill Oswald in the Dallas PD basement.

I’m glad the documents are out. I hope to read many of them over time. The myriad conspiracy theories they are likely to rekindle are the work of people with too damn much time on their hands.

They need to find work. They need to get and stay busy.
