Hmmm. Kind of a knee-jerk reaction to toss a vote for Cory Lover this early in Day 2, isn't it? It seems unlikely to me that the mafia would have pegged Ice's true identity so soon; their hit on the detective was probably just lucky.
The mafia probably predicted the townies' reaction to lynch Cory Lover, as Ice was hot on his trail (for the only reason that Cory Lover claimed to be an innocent). It was only Day 1, and any case against anyone was pretty weak. Whacking anyone for getting 'too close' seems a little unlikely at this point in time.
I'm not telling folks not to vote for Cory Lover, just keep looking carefully elsewhere at the same time. Don't let let the fact that the detective got whacked cloud your judgement.
