That dash cam video, and others I'm sure we've all seen, display the very worst that the LE profession has to offer. I believe, however, that officers like the one depicted in this video are the exception - not the rule.
This also illustrates how important it is for concealed license holders to conduct themselves in a manner that is above reproach. When we have such a license and carry our weapons, our actions... and reactions... reflect not only on ourselves but also on every other licensee in America. Statistically, license holders are by far the most law abiding citizens in the nation.
An officer's job is to observe people - how they look, dress, drive, who they're with, where they are, when they're there, what they're doing, how they're doing it, and how all of this "fits" in the situation when considered as a whole. It's a dangerous and difficult job. The dedication, service, and sacrifice of good officers and their families are things that I appreciate.
