I would do it privately too, at first... but it has been several years already and the damage is still outstanding. I'm not angry, I'm just disgusted and disappointed when it comes up. If I didn't care about the community, it wouldn't bother me... but when the village you love is infested with rats, it's disheartening... especially when a bunch of the villagers would rather pretend that they're wonderful pets rather than the diseased vermin they are.
I realize you're in a delicate position because of your business though. I'll definitely hit you up for a beer one day. Conversations like this are always so much better in person. I have friends in Panama and a visit would certainly be in order. :)
