I doubt anything significant will happen. George HW is still alive, and would have been the president who signed the bill from congress. He was also possibly in Dallas and a part of the assassination according to some.
Can't say if that's him standing outside the book depository, but can't say it isn't either. And the men stand the same. Bush had his hands in his pocket a lot.
Bottom line: much ado about nothing
Yup I saw that too!
