There are no forum rules, Wiki Silicon Policy rules, or explicit Rule-Page rules which states that dead bodies are protected under Law 2. That said, there’s nothing that explicitly states that they aren’t.
Silicons are expected to follow Law 2, unless it conflicts with Law 1. I’d personally argue that the above situation does not, since “harm” is generally defined throughout the above three documents as relating to immediate, or self-evidently imminent harm. In the case of a corpse - the harm has already been done. Past-tense.
Silicons are robots - they act purely on an input/output basis, depending on their laws. Instead of asking what was up, it would likely have been better to just give a buzz, and state something like “Processing Potential Law 2 Conflict”. It’s up to organics to input a query or provide supporting logic, it’s not the place of a silicon to directly question orders. That’s just my opinion, though.
The person who killed you - if not an antagonist - was definitely in the wrong. If there is an issue with a silicon which doesn’t present an immediate, clear, and present danger to oneself (if one is not Security) or the crew (if one is Security) - the favored method should be a lockdown and examination of the silicon’s laws.
Additionally, given the ambiguity of the situation above, a ruling regarding Crewsimov Law 2 relating to corpses would be appreciated. It seems like a common enough happenstance to warrant a ruling.
