Well, it seems people are arguing over Chaco's cop claim as being true or not. I know I'm re-stating the obvious, but here are the possibilities:
Chaco is the cop, and he was roleblocked.
Chaco is scum, pretending to be the cop.
Do we know how many people are scum in this game? This affects the rest of my post. I will assume three, but if it is different, let me know.
We have already removed one of the three scum in the game on the first day (while losing two town), so we're left with 2 scum and 10 town. If there is another cop, then if they claim, we will know for sure that Chaco is scum and can vote him out today. This will result in only 1 scum left and 9 town (scum nightkilling town). This would be incredible odds for town. So that said, if there is another cop, in my opinion, you should claim, thus the above will take place, and we'll be left with only one scum left.
If no cop claims, then we can't prove his cop claim false (though this doesn't necessarily mean it is false). All I'm saying is that now would, in my opinion, be an excellent time to claim cop, since we'll be guaranteed lynching scum today.
my two cents on this topic.
