In firing squads, one rifle holds a blank to preserve the possibility in the hearts of the shooters that theirs was not the shot that killed.

I imagine blind voting would also serve to assuage the worries of legislators. If only we knew what each worried about.

Firing squad members don’t usually fire more than one bullet, and it’s very obvious if your case was blank or not.
