This mistake was known for the last couple of days and he apologizes now? He probably heard the couple lawyered up and plan on suing his ass to kingdom come. This delay will be noted in court - if in fact it did just come out, I don’t do twitter so I can’t tell.
My guess is that Spike's lawyer told him that if anything happens to this couple, they will own his ass.
I doubt he gives a crap what happens to a couple of old white people. He just doesn't want to lose all his stuff over it and some lawyer finally told the dumb SOB that is exactly what would (and still could) happen.
Who thinks all his idiot Tweeter followers got the second message?
