Nope, not when there is a specific law addressing it. It is a felony to try and influence a Sitting judges’decision by protesting outside their home. Go to the court and protest. Blatant display once again of leftist hypocrisy and bully tactics.
As far as carrying a gun, I guess it wouldn’t have been a problem until he told them he wanted to kill the judge. That speaks to intent and means. Guilty, not protected.
