Bad Call??

[just another ref]

according to my wife, I just like to argue. This is true, too, but that is another story. I am saying that you can't have it both ways. Many times the question is about a judgment call. "Oh my gosh!! Did you see that?? That was no travel!!!" Then they turn to me. (or whoever they may deem competent on the subject.....there's a compliment in there somewhere, I think) "Was it?" If I agree with the call, I quickly say so. "Yes, I thought it was a good call." If I disagree, I try to be diplomatic. "Hard to say from here." But, when the question is about a rule and people ask, I find it hard not to answer. People know that I know, or should know, the answer, which is why they asked me in the first place. If I give no answer, are the officials not, in effect, condemned by my silence?
