I think it's worth remembering that this is an elected position, and this sheriff is overwhelmingly popular, to the point where he ran unopposed in the last election. Per the Tampa Bay Times:

Nocco's uncontested re-election in 2016 is indicative of the sheriff's popularity, his political prowess and the county's continued tilt to the right, which puts Democrats at a decided disadvantage during general elections. Pasco's current registration numbers show the Republican Party with a 21,000-voter advantage over Democrats.

"I'm incredibly blessed that the citizens have so much faith in what we're doing,'' Nocco said about an uncontested re-election.

In short, no improvement can be expected when the voters themselves support this kind of authoritarian overreach and curtailment of human rights.
