Perhaps it's because I kept threatening to kill someone who they knew wasn't mafia?
I believe your two targets that you were deciding between were DJ and Bad Ash? Looks like you were targeting a scum and a rolecop (who I'm leaning slightly town on, but may in fact be scum). It's very possible that you were talking about shooting only scum, but you're still alive. That's why we're confused ... I'm not sure why it would confuse you so much.
