Tasspook, I am trying to see what CHC can do about any of those things? CHC can hardly go and arrest suspects can they? Build a house with higher walls, more private security, more guns?
When you chose to come and work in Africa (and other parts of the world but I know which incidents you refer to) you get extra money for the risks you face. If the money doesn't equate to the risk you think you're facing, go and work in a developed world country but don't complain about the lower money. There is very little that the helicopter operators (any of them) can do about the overall political stability or petty crime within the countries it operates in.
I take your point about your seemingly crazy pilot with a gun though. That's not right.
