See, I get that part. Whether the person simply has no experience with guns or is anti-gun as you portray him to be I would expect some level of unwarranted anxiety.
What I'm not quite understanding is why an experienced gun owner would advise to contact the authorities, personally consult with a retired NYS trooper for advice, consider if it's best to find a responsible gun owner to take charge of the cartridge, seek further input on the Net for disposition, and lapse into a situational awareness lecture with the kids. Where is all this coming from?
