Eh, I thought you guys were just purely saying it would never be ok to shoot someone beating you/someone else up. Probably a misinterpretation on my part.
Is it possible that Zim was just trying to stop TM to ask him who he was and what business he had there because he did fit the profile of previous break in reports and that TM did get pissed off about it and started beating up Zim and he defended himself, albeit, extremely?
