My apologies I made a mistake. The Burdick SCOTUS case from 1915 said “carries an imputation of guilt and acceptance of a confession of it”
In 2021, an appeals court opined that: “not every acceptance of a pardon constitutes a confession of guilt.”
I thought the 2021 case was a Supreme Court case, and I was incorrect. I think in the public eye the pardon is viewed differently based on however the story is told.
