I don't think we should be informed about the one BG has protected, rules seem clear to me, it was our bad in the previous games as Aaron said.
The fact that the BG knows it will be enough for us. If he/she protected him/herself last night, it means that the gangsters know who the BG is, so the BG should tell us publicly about his/her role as there is no point in hiding that anymore. But if the BG protected someone else last night, he/she should keep on keeping his/her role to him/herself (damn these all his' and hers'

)
Osman, you said last night that you checked your sent items and you noticed you'd sent the pm to Sabet instead of SABSAB, right?
