Town for scum is a good trade. End. Of.
It doesn't matter if you think you're a gr9 player and everyone should sheep you, or if you think that your 50% clears and 50% chance of detecting scum are so valuable that you simply cannot sacrifice yourself. If cop claims here, we get a HUGE advantage. It allows scum to die BEFORE we get our chance to (probably) lynch multiple times d2. In fact we could slaughter a scumteam before d2's dawn. If cop doesn't claim here, scum WILL be treated as conftown, we will probably go and lynch town today, and when you attempt to CC later you will get lynched.
pedit: Actually I wasn't really joking at all
