I don’t know about you people, but when I read this I couldn’t help to wonder:
The rules of Safaris are pretty simple, if you want to go somewhere filled with wild animals you are never to leave your car + your guide is always armed.
I don’t know, I can’t imagine chimps (even in hordes) can open a car and take out the people and beat them up.
I am inclined to thinking that maybe the group crossed the line (as usual). Now of course the death of the driver saddens me, but what was he thinking? Now the chimps might get killed for this incident.
