Like him or lump him, Grossman has really perpetuated the whole us vs them, warrior mentality with LE. I am not sure where I stand on it; a lot of cops I know are uncomfortable with the label.
His "sheep, sheepdog, wolf" thing sounds great, but it became a means of denigrating members of society while elevating others. It became a social perception instead of an analogy for what amounts to a division of labor. I remember how people who blindly followed others were lemmings, but now they are sheep. That can't be a coincidence.
I partially blame how we put veterans on an impossibly high pedestal because it perpetuated, and some revel in it, the sheep/ sheepdog social distinction. While I'm conservative, my fellow conservatives did this. Liberals aren't talking about sheep or sheepdogs...at least not in large numbers. Anecdotally, I don't know of a single left-leaning person to say they are a sheepdog.
