It is not free or protected speech to threaten someone outside their home.
There's a sex offender a short walk from my home. I was sickened when I found out he was living right near me. There's been concern over the years he could strike again. As disgusted as i am with him and his crimes, I don't stand outside his house and threaten him because you don't do that regardless of how I might feel about him.
Tucker Carlson may or may not be your cup of tea. You may find what he stands for deplorable and everything against what you believe is decent. You still don't stand outside his home and threaten him at his residence.
Our world has lost its mind. It really has. This is a huge story. NOBODY should be threatened outside of their home in this country. The worst of the worst are afforded certain protections.
