All right Woodbutcher, there was no second shooter. The sound that you heard coming from the grassy knowl was not from a gun. Swamp gas from a weather ballon was trapped in a thermal pocket and reflected the sound from Uranus.
The reason I mentioned the JFK were two reasons. I watched the Chapaquidick movie over the weekend on Netflix. I would recommend. Also, I was watching “The Lost Kennedy Assassination Tapes” on the National Geographic channel yesterday. There was a lot of footage that I had never seen before.
