There is no need for a press conf to apologise, Jack only need to apologise to his wife and kids not to others. This is his personal life. .
bro, you forgot one very important point ... JN is a celebrity. As such he has a duty to apologize to his many loyal fans, advertisers and supporters, etc. Popular celebrities actually belong to the society since they make their incomes from them, and they are role models for them too :dunno:
If it was you, then you really do not need all these wayang interviews/press conferences ....
