In my 1982 training they told us that a USFS inspector found a pot field and was confronted by the grower with a shotgun but talked his way out of it by explaining that he only was interested in fire conditions and obv. the grower didn't want his crop to burn but then a week later the Mendo sheriff launched a pre-planned raid so the grower assumed the USFS guy had narced and a month later a FS helicopter was downed by rifle fire that hit the engine and the FS elected to report it as merely an engine malfunction because they didn't want to do Hatfields & McCoys.
This wisdom has remained with me and informed both my jaw and mediation practices for nearly 40 years now.
