To be perfectly honest, I've never thought it was a conspiracy, and that was before I'd done any research on the subject. As a child, I just took it for granted that what was in my history books was accurate. (Yeah, I know. I was young!) I discovered the idea of conspiracism as an adult, though I remember the hoo-ha when JFK came out, so I knew of it as it related to JFK before then. I just didn't think much about it. However, as I've gotten older, I've actually done quite a bit of reading on the subject, and I have never come across anything which has changed my childhood view. I don't know how important a factor this is, but all the smartest people I know--including a beloved history teacher--believe Oswald acted alone.
