At the moment we haven't documented those cases sufficiently to be able to speak to them. It would be very worth your while to have a look at the statement from the United Nations working group on the use of mercenaries. They'll be issuing a more thorough report later on.
The statement itself is quite interesting in relation to the use of private security guards. The location in which we've seen some of the reports is the Aguán, so obviously some of those security firms work in those areas on behalf of local landowners, but we have not documented those human rights violations sufficiently to speak to them. The ones we've heard about certainly stem from the Aguán.
