The documentary you mentioned sounds very interesting, I'd like to watch it at some point. What was it called and can it be found on youtube ?
To be honest I'm a little shocked with the ethical dimensions of what the journalist did with the chimpanzee meat but I totally agree it does indeed prove a point and sometimes things which seem ethically questionable can be valuable illustrations.
The documentary is in fact available on YouTube. It is mostly in Dutch with some parts in French, and I don't know how good the subtitles are.
I found the buying of bushmeat and especially the buying and smuggling of the chimpanzee meat very disturbing. I wish they had been able to show the extent of the issue in a different way.
