Well, yes. And, no. Elected sheriffs represent a stopgap of sorts. Some push back CAN prevent the necessity of armed resistance by 'the militia(s)'. Unfortunately, for now, the concept of militia is poorly understood. But the real necessity of a citizenry ready to preserve and to exercise -- by whatever means necessary -- recognized and codified unalienable rights that are endowed by Creator (Life, Liberty, and The Pursuit of Happiness) rests solely in the hands of those who consent to be governed. The sheriff is ideally one of those 'consent-ers'.
