Legal Question in Criminal Law in California

Re: Blackmail Vs. Extortion

EXTORTION

n. obtaining money or property by threat to a victim's property or loved ones, intimidation, or false claim of a right (such as pretending to be an IRS agent). It is a felony in all states, except that a direct threat to harm the victim is usually treated as the crime of robbery. Blackmail is a form of extortion in which the threat is to expose embarrassing, damaging information to family, friends or the public.

BLACKMAIL

n. the crime of threatening to reveal embarrassing, disgraceful or damaging facts (or rumors) about a person to the public, family, spouse or associates unless paid off to not carry out the threat. It is one form of extortion (which may include other threats such as physical harm or damage to property).

I hope you won the argument!
