--IMHO, the chiefs usually are subservient to an anti-gun Demotraitor mayor who controls the budget the chief works under -and usually the chief's longevity in the job, too--
In some cases. The man who is currently our CoP is appointed, has outlasted several mayors and city councils, and is virulently anti-gun. He has a display case of confiscated guns in the police station. His officers aren't very fond of his attitude, but manage to work around it.
For the record, we are a smallish border town of about 45,000 serving a military installation and retirement community.
