The affidavit of Johnny Brewer makes no mention of Oswald having a gun, let alone trying to shoot an officer with one. Strange detail to leave out of an affidavit?
Johnny Brewer's affidavit: https://texashistory.unt.edu/ark:/67531/metapth339626/m1/1/
Notice that Brewer's affidavit is dated December 6 , 1963..... Two weeks after the event.... That affidavit isn't worth spit.
However Brewer did make a couple of interesting statements in his affidavit.... He said that he followed the man up the street to the Texas Theater....This is in sharp contradiction to his testimony.....in which he said he saw the man go out of sight in the foyer of the theater and then he went back into his shoe store ....In reality Brewer could not have known if the man had actually entered the theater ......Another glaring cntradiction is he said that he had heard on the radio at 1:30 that a police officer had been shot. He made that up.... Because there were no radio reports of the Tippit shooting as early as 1:30.
Brewer said that he saw a man (LHO) at the rear of the theater stand up when the lights in the theater came on and the man remained standing until officer Nick Mc Donald approached ....
Brewers last sentence says that he noticed the man looking in the window of his shoe shop was because he was nervous and therefore he thought the man might have been the man who shot the policeman. This last sentence is pure BS.... Brewer never knew about Tippit being shot at the time the man was looking in his shop window.
