It's really sad to see that sort of vandalism. Not to diminish this incident, but we had some really nasty vandalism here on the big island several years back where papaya orchards were being attacked and farms suffered losses ranging from hundreds to thousands of papaya trees. I had to drive by one of these farms down in Puna -- it was a horrible sight and was really disturbing. There were all sorts of rumors at the time from competitors to family issues to environmental wackos (some of the papaya here is genetically modified); I'm not sure these cases were ever solved. Hopefully, they'll get the person(s) responsible for this one.
