If it was my decision, no. If I was one of the best employees at my company and management tried to frame me over an incident that never happened, then never owned up to their mistake, I wouldn't show up at a company anniversary ceremony. If I ever had any second thoughts, I would re-read the case they made against me and how they went from saying I was generally aware of something to masterminding and directing a scheme without introducing any new evidence (or any evidence, at all, really) to support that. And if someone asked why I wasn't going, I would tell them the truth.
Having said all that, I think there's a chance Brady attends. He's got a lot more class than I do.
