If you had a greater grasp of their Constitutional authority, perhaps you' understand.
Then again, you might be right in that it's a regional thing.
Don't confuse your States, wherever that may be, with others. In most States, a "Sheriff" has no more legitimate authority than any other LEO. In Texas, for instance, all LEO's have EXACTLY the same authority and jurisdiction. The difference is that a Sheriff is tasked, by law, with jailing prisoners.
