Honestly, pola sent me a sitemail telling me that "the funny thing is aggie is the cop", or something along those lines. I used my messages between he and i, and sent them to aggie, in the case that he really was the cop, but also to create doubt among pola and you in aggies mind.
I seriously thought that you would save yourself, and figured that if I went after aggie, after pola told me aggie was the cop, it would look mighty suspicious. I had HOPED to off pola, and thus create reasonable doubt in aggies mind and still win the game for the mafia.
