Every once in a while this happens.
Could be drugs, or Billy Bob screwed Rufu’s old lady.
Back in late 2019 or so, a small town in the Berkshire Hills in western MA, maybe a bit larger, had their entire force resign. It was a mostly centered on the town being usable to provide equipment. They had used Crown Vics, their one 4x4 vehicle was not worth repair, radios were outdated and had very poor coverage in many parts of town in addition to low pay.
In the end they merged with 2 or 3 smaller surrounding depts to combine resources to have better vehicles, staffing, training and joined a regional dispatch and radio system for better coverage.
