Brown was out of order. Civility under such circumstances is a must. Brown could have made his feelings known in a more appropriate manner and by doing so may have gained some credability.

In turn while I understand the mannr of interaction from folks who live in New York City and New Jersey christie also could have gained much by not using the word idiot and instead made some comment about protocol, etc. What christie ended up doing was attacking the person and not the inappropriate appraoch Brown used.

But again a speaker is under pressure and stress in many of these public appearances trying to provide a solution to such a diverse group and so it is human to error.
