Sheriff Ian Parkinson was acting within the scope of his duties when he wrote a letter to Vice President Joe Biden regarding gun control. Despite what has been written by many (including The Tribunes own editorial staff), federal gun control laws are not state laws, and thus the sheriff, as a California law enforcement executive, is not mandated to enforce them.
In fact, in many cases California law enforcement officers are prohibited from enforcing federal law (such as immigration laws). Further, the sheriff has taken an oath to uphold the Constitution. As the Second Amendment has not been repealed, the sheriff must support and defend it.
Sheriff Parkinsons letter to the vice president simply reiterated the stance taken by the California State Sheriffs Association, which represents every sheriff in California. I respect and commend Sheriff Parkinsons stance to not make law-abiding citizens into criminals. If people are so preoccupied with the sheriff enforcing federal laws, perhaps we should start with federal drug laws. After all, more people die from drug overdoses than firearms use.
