I was in the 8th grade on November 22, 1963. When we returned to classes after lunch, the teachers were acting strange (well stranger than usual).
Mr Marksbury, the history teacher, told us to read a chapter and kept going in and out of the room. My next class, our English teacher, a woman in her early twenties (this was her first teaching assignment) - didn't come into class until almost 10 minutes after the bell rang, and she was crying....she also told us to read....and left soon afterwards.
Last class of the day was Science with Mr Alexander. We went in, sat down, and he didn't say a word. Finally a girl in class named Karla Doty raised her hand and said: "The radio said they shot President, is that true?"
We were all shocked. Karla had a transistor radio and had turned it on during English class. Mr Alexander just said: "We'll have an announcement in a minute."
The intercom crackled on, and our principal Mr Boyd said: "President Kennedy was shot in Dallas, Texas, today. He died an hour later. Students are dismissed for the day."
I think there was more than one rifle. But I don't think we'll ever know for sure. Theorists always skew the facts to fit their own theory.
I don't know.
