Hi, Rick. Always good to chat.
Mr. Alphahole raised the prospect that calling someone a "Dirty Bum", if heard by a LEO, could result in a felony charge being brought against the speaker. He has since broadened that concept substantially to expand to actual conflict and "mutual combat", while professing that CA does not have a "stand your ground" concept legally in place.
Setting aside the stand your ground issue, (and ignoring the fact that calling someone a "Dirty Bum" doesn't seem to rise to the levels of CA PEN 422), since 422 is a wobbler, how many of the CA PEN 422 you saw were charged as a felony?
IMHO, PC 422 is probably one of the most mis-used Penal Code sections out there, and the misuse is both by LEOs and prosecutors. The legislature carefully crafted the text of the statute to be respectful of speech rights, while criminalizing clearly threatening behavior. The elements of "Immediate execution" and "sustained fear" were intended to preclude most forms of angry speech as being a violation.
As a watch commander, I'd occasionally have a patrol deputy bring in a 422 arrest for review and explain that the suspect said "I'm going to kill you" to the victim as satisfying the elements. I'd ask "what did the victim do" as a result of the threat. If the response was "well, he called to make the report". I'd deny booking on that charge. The reason being is that there was no fear of "immediate execution" and that only an ordinary (as opposed to "sustained") fear was present. OTOH, if the deputy were to explain that the victim fled to the station lobby, refused to return home, paid off his burial plot, and requested last rights from his priest, then I would approve booking on the charge.
But, in actuality, PC 422 has become something of a last resort. In cases where someone really needs to go to jail, and there isn't anything better to charge, then PC 422 goes on the table. Prosecutors sometimes evaluate cases on the same terms and that produces filings.
Most of the 422 arrests that I've seen have been rejected for filing, probably for the reasons stated above. Where the reports clearly addressed the elements, and there were not any complicating factors, I'd see misdemeanor filings. Egregious, repeat, or gang offenders would sometimes get the felony filing.
But the "Real World" issue with a "Wobbler" offense is that it is a felony, and nothing less than a felony, until it actually "Wobbles" (generally the 2nd court day following the arrest). That means you go to jail for a felony, get put in a felony cell, get felony bail. and do not get a misdemeanor cite-out. That may all change after two days, but those are going to be very long days.
