I'm with you, no physical violence against GZ.
I think people should organize into a group of watchers and followers. Every time GZ leaves the house, he gets followed. When he goes into a store, someone follows, when he leaves for his job someone follows, when he walks his dog someone follows. If GZ turn to look at the follower, that person puts cell phone to ear as if making a call. If GZ looks at the follower, that person pats his pocket as if to indicate a concealed carry weapon.
Let's see how the creepy-assed cracker likes it when the tables are turned. I don't support killing him but I'm fine with gaslighting him.
