There are some people here on WS who think BL might still be inside his parents' house. That's how crazy this case is. <modsnip>, because if the FBI can't get to him inside that house (so far), and is behaving as if he isn't there, it's unlikely the randos with bullhorns and shouting are going to get the family to cooperate with LE.
I do think people like showing up in videos on Twitter, though. A lot. I used to follow a lot of celebrity trials and was amazed to show up for 1-2 days of trial watching or trial crowd watching if I couldn't get in, and see the same people - even if it was in a different state. I was taking notes (this was before cell phones) and had a little digital camera. I came up with names for these characters, so I could note how many times I saw them. Some of them just wouldn't quit and I'd see them on TV in other states, at another celebrity trial.
Crime groupies are a thing. There is crime tourism, for example.
