Just a thought, but ...
Imagine you are someone who is contactable on local matters by the local newspaper, and something like this happens in your area.
And say the police ask you to help and, consequentially, arrange an appointment whereby you can hand in a weapon. And, to push the hypothetical scenario a bit further, say you were in the position to hand in another weapon at some point in the future ... you'd probably ring up and arrange an appointment with the same person who entrusted you to do so before, wouldn't you?
Just saying, is all.
