As you said "Turns out the officer was super friendly and genuinely interested in it and came to take a look at it" He was just interested and he was tasked by the Sgt, to followup on the report, not unusual at all. I am a retired LEO and Neighbor complaints are a PIA, by nice to you neighbor guy's and Gal's, I have seen some nasty wars jump off. Killing pets, pouring Roundup on trees and shrubs that crossed property lines, one guy even hired a surveyor to check property lines, found the neighbors pool was 1 foot inside his easement, and took him to court to move it. By coming out to check he can contact the RP and tell them no laws were broken.
