My guns are always welcome home. Always. End of story.
I understand how you feel, but put this in perspective, which you seem to have lost, being so focused on getting your gun back.
You yourself said it wasn’t expensive, you are upset because things aren’t the way you want them to be — well, that happens a lot in life.
Be glad they caught the perp and your gun helped put them away — so it accomplished a good thing.
Just move on, instead of wasting your energy on this.
