That is me, Colin. I'm the sane cop and I targeted Aditya last night as well. That'd explain the whirling lights the departing guy (the roleblocker, now I think) saw while leaving. He had blocked me, but you were also investigating Aditya, so he had some explaining to do. I targeted Bevab last night and got him anti-town which confirms my sanity.
Due to lack of results last night, I was hesitant to claim because I felt I was the only cop out there. You were right about me holding myself back, because I didn't want to even give a slight signal to anyone that I'm the cop. That's why I mostly stayed away from insane-sane cop discussion. I was sure Bevab wasn't the miller, and I was sane - he gave himself away somehow despite his claim. But still I didn't give any vibes that I had investigated him. Sedition and Zhuorb both have gone down because they were thought cops by the mafia (Sedition used that cop reverse-psychology thing and Zhuorb lynched Bevab right after Night 1). Although I did post some facts that I indirectly knew from my role, in order to bring them up in case someone counterclaims cop and tries to get me lynched. I posted twice that there had to be an individually aligned player in the game - which I knew from that I get [Pro-Town] or [Anti-Town] results. The [] brackets should also convince you, Colin, pd should've used the same in your PM.
I wouldn't have been convinced by your claim, but those two paragraphs point towards it being true. I was most puzzled initially about the 'whirling lights' which signified that an investigation had nevertheless occurred despite me being roleblocked. But you being cop explains it.
