Also, since he was lynched I forgot that I never explained why SKs should absolutely never be leashed. An exposed SK knows that they'll have to be lynched at some point, so it is in their best interest to try to take out town so that the numbers become such that town can't lynch the SK or they would lose to mafia. Mafia might lose a member or two in the process, but the extra townie kills from the SK also help get the numbers down faster, bringing mylo/lylo earlier than they could alone. And going by the information radish gave and the assumption that all mafia are humans, lynching radish was the only choice, because it would immediately drop the number of night kills.
I didn't bring this up Night 2, because had the lot of you decided to play with fire I was going to block radish anyway.
