I'll attest to this. About 6 years ago on a coast-to-coast radio broadcast, the topic was the RFK shooting by Sirhan Sirhan (I'd like to hear his side of the story before he dies). In any event the guest invited callers to phone in with thier recollections of the event.
I was absolutely sure I saw the RFK shooting "live" on TV, so I called in. It didn't happen that way: In short order I was corrected, the fact was that the shooting wasn't broadcast for a day or two. OTOH my mother-in-law insists she saw JFK get shot on live TV. I have tried to explain she only seen the Zabruder (sic) film; NO she insists she was watching TV when it happened. There is no convicing her otherwise.
Yes, our memories are faulty. However, the South tower was hit second and fell first. The North tower had the flag atop of it.
Sometimes it startles me, the rage. It's so intense, so overwhelming that I'm left shaken. It is almost a year and yet it is as intense as it was on the first day. I will not let go of it, not until the last terrorist is in his grave. Then I will mourn, until then I will stay angry.
