Back in the misty deeps of time a close friend worked for Bolt, Beranek and Newman, in Cambridge, MA. BBN were the people to go to for acoustic analysis of, oh, say, submarine propellers, or nuclear reactors. They were contracted in the 1970s by some federal agency or other to analyze the so-called “dictabelt recording”. Said friend, an electronics engineer, spent a couple of weeks in Dallas setting up microphones and recorders and setting off firecrackers in a myriad of locations trying to duplicate the signature that was on that dictabelt. Bottom line, the only configuration that worked included a shooter on the grassy knoll. The team submitted their report, and according to said friend they were told to destroy it and STFU. All I know, but I do know that.

If you’ve ever been to Dealey Plaza and stood where Zapruder was filming, you’d know that the idea of someone firing a high-powered rifle from the grassy knoll, and hitting a moving target on Elm Street is ridiculous for numerous reasons. Namely, Zapruder doesn’t jump and move the camera during the third shot.

The grassy knoll is only several feet to the right of the pedestal Zapruder was standing on.
