So you would rather an unarmed neighbourhood car attended, because non attendance should not be an option? And on arrival discover the report is a couple of Albanian drug dealers hiding their stash in the woods? Or a couple of blokes testing their reactivated/printed firearms? Or a couple of extreme right wing or Islamist potential terrorists “training in the woods”? Or even a couple of miscreants had hit the OP over the head and stolen their firearms?
Fact is, the police attended a “firearms call”, they would have been remiss in attending any other way. As the OP said, the police were polite, efficient and when discovered there were. I offences apologised for the inconvenience. Where’s the issue?
“We who live in the country…” no, stuff is different now. My first magnum revolver was delivered to my door by the postman, long since done.
And yes, I’ve have had guns pointed at me before and I have had the police respond to me on my permission. Expect it, or stay on the target range.
