Parker is guilty of assault--I don't think there is any question of that--and I don't think he's pals of our Dear Governor any longer because of SB 610.
At the beginning of the thread, with "I'll be your worst nightmare", no. Threatening to be a politician's "worst nightmare" could easily be a political challenge or, even worse, a recall petition, both legal.
After this? "When you see me again, you best walk the other way lest I beat your little ass with my bare hands.”
Yep, that's assault. Might even have something to do with stalking when combined with the worst nightmare threat.
