It doesn’t look like Bush. Hairline and shape of chin are different.
You are looking at about 10 years worth of difference between the 2 pictures.
Maybe it isn’t Bush. But he was scheduled to speak that night or the next night and so he was in the city. But he sent in a phone call “tip” that was really stupid for a CIA guy, from “Houston,” so it looked like he wasn’t in Dallas.
PAnd since then, he has said he doesn’t remember where he was on the day Kennedy was shot. That is bull apples!!! No one wouldn’t remember, especially him.
