Some how I don't think that this will happen receiving any apology, depending on how much you need the job, I might be inclined to let it go...To me
its obvious the guy has some personal issues going on and you just happened to be in the line of fire, things could blow over in a few weeks.
Therefore, if I want to keep my job, which I do because it is close to my house (gas prices), the job market has slowed down (not a good time to be unemployed) and, I'm not in the best frame of mind to be starting a new job (going through alot of changes mentally after leaving org. after 20 years) I do have to have this matter settled. I plan on telling Vince that I don't approve of Gerry's behavior, that is was/is unacceptable. That I expect nothing less than a public apology. I also need an apology from him (Vince) for not interceding in my behalf, since he as an employer is obligated to provide a safe environment
But you did barge in his office and give it back, your sorta even there.
I wish you the best
just my two cents
