What did he really do? Was he drunk driving or just smelled like alcohol?
He was pulled over for an unsafe lane change or something, if I am not mistaken.
Most officers would have let another officer go unless he was driving while intoxicated or wanted to make an example out of him!!
And, yes, I think it is OK to have a beer at a dept BBQ or training day then drive the take home vehicle to your residence as long as you are not drunk driving!!

It is easier to be critical than correct and most people tend to take the easy way!
