Keep the feed. Consider it a public service.
My county is also about 17K population and normally peaceful. I average 2-3 users on my feed, usually local volunteer fire chiefs or officers whose day job requires that they work out of their districts but who have the ability to keep tabs on activity via their smartphone or office computer. It is a way of knowing when they should trend towards home (or not) if it hits the fan and they're out of radio range.
Joplin, MO has 5 listeners right now (I just checked). 9,000 users were online a year ago in May.
While the majority of Joplin listeners were casual users, I suspect a sizeable portion of them were responders, officials and others actually involved in the recovery and mitigation. It wouldn't suprise me that the SEMA communications desk a hundred miles away in Jefferson City, or FEMA regional coordinators were among them. During a major incident, radios will be in short supply. Internet is plentiful.
Yes, there are officials out there that discourage communications transparency, legitimate needs for communications security, and abuse of the system by those operating in the "gray areas" of the law. That said, there are also tremendous benefits. Lindsay Blanton is to be congratulated for providing a valuable service to the responder community.
