There are so many suspicious things about his life since he'd been a fugitive. Walking around Santa Monica like Jack Tripper for all those years. Out of nowhere, he's suddenly arrested. The timeline since then makes his arrest seem more suspicious than his time on the lam. Everyone knew why he was free all of that time. You don't even have to be a beginners' level conspiracy theorist. It's the arrest that's puzzling. Why then? Then he's killed at age 89. As someone said earlier, there are snitches with as much notoriety as him walking around without a care in the world, like Gravano. I don't buy it was revenge for the snitching or anything like that. So, what does that leave? What is the one remaining threat he could pose to anyone?
