ijusluvit - i believe the sister of the victim indicated that the story as written by the post was "'factually incorrect' and that they are '"aggrieved that he would be used to further a political agenda.'" that sounds a bit stronger than your description of "regretting that the matter has been dredged up."
Family: Story about Romney prank on brother 'factually incorrect,' politically motivated | Fox News

you also posted, "'The four others who ganged up on the kid and cut his bleached-blond hair remember this incident well." and today other classmates have different recollections of mitt romney, "Mr. Lauber is no longer alive, but several classmates confirmed the account. Others, in interviews on Thursday, said that they were surprised by the accusations, and that they had never known Mr. Romney to act in a vicious or cruel manner.

“'One of the last words I would ever use to describe Mitt would be bully,” said John French, a Cranbrook classmate. “If you’ve ever been around guys in a boys’ school, you kid each other and pull little pranks on things, what you might call sophomoric humor, but I really, honestly, do not remember anything being malicious.'”

it's unfortunate that mr. lauber has passed and cannot be reached by the wp/nyt for his interpretation of the event!

did mitt romney lie about not remembering - who knows? maybe the other classmates have better memories. maybe mitt blocked it out of his memory. you don't know if he lied either!

i can't remember everything about 1965 - except that as a h.s. senior i got my driver's license on the first try and then skipped school for the rest of the day. when it got found out - i got detention; it was the FIRST time i EVER got after school detention! and when i told my father he replied, "thank goodness! college admissions officers might have thought there was something wrong with you!"
