Mac Wallace was a close associate of LBJ.  By “associate,” what I mean is: hitman.  There is substantial evidence that links multiple murders to LBJ by way of Mac Wallace.  Author Roger Stone makes the claim that Mac Wallace may well have been one of the shooters in Dealey Plaza on 11/22/63.  You will also notice in this video that Brown & Root/KBR/Halliburton are briefly mentioned.  To read about my thoughts on that matter, please follow the following link: https://medium.com/@StarWarsChief/jfk-9-11-whats-the-connection-238a38f39b47
