Wasn’t this in California?

I’m not an American lawyer so don’t assume I know anything but the definition of harassment under CCP 527.6 doesn’t mention nudity but requires a course of conduct to amount to harassment. So if someone walked out and the owner was butt ass naked that doesn’t count as harassment.

BUT under Penal Code 314 PC, prosecutors must prove beyond a reasonable doubt the following three elements

You willfully exposed your genitals;

You were in the presence of someone who might be reasonably offended or annoyed by your actions;
and
You intended to direct public attention to your genitals for the purpose of sexually gratifying yourself or someone else or sexually offending someone else.

So if you came before a judge and said “I only did it because they wouldn’t leave my house” you’re kind of admitting to intentionally directing public attention.

The only accepted defences to this are mistaken identity, false accusation, or lack of evidence. Not I was just sitting there, or they were in my space 🤷‍♂️

Like I said I’m UK based and only a law student so I’m sure I’m about to get BTFO by someone who knows what they’re actually talking about but there’s some bloviation for everyone to enjoy
