Advice to call cops on elderly dad

More bad Dear Annie advice:

Dear Annie: I need your advice ... My grandfather's 100th birthday is coming up, and my uncle arranged a big party. Needless to say, the entire extended family is expected to attend. I will go and remain cordial to my father for Grandpa's sake, but what do I do if he rages and tries to assault someone? — Worried Sick

Dear Worried: If Dad assaults anyone, call the police immediately. Do not get into a physical altercation with him. Make it about a crime being committed.

No, this is crazy advice. These advice-givers are sick and demented. You do not goto a family party with the intention to have your elderly dad arrested for his bad behavior. Surely Worried'd husband and the other male relatives are capable of restraining an old man, if necessary.
