Tough spot to be in for the department. Neighbor makes a claim he's being threatened,....
1) make a visit and do nothing else....
A) neighbors fight for years, no big deal.
B ) complaining neighbor gets shot....lawsuit follows for lack of action on complaint.
2) make visit to cranky old vet and assess his mental state....
A) he's violent and angry, temporarily remove weapons, face criticism from 2A group
B )seems normal, complaining neighbor is a dick. Leave....refer back to option 1
It sounds like a shitty case, but I don't know this vet and can't give him the benefit just because he is a vet. There are many levels of crazy people and assholes all over the world in some of the most respected positions. Sounds like he is regularly into his neighbor's affairs...and probably well deserved. Just strikes me as odd to call the cops claiming to smell toxic chemicals.
