I'm actually writing a legal article on this subject right now, and from the immense amount of research I've done, I've actually found this report to be quite accurate.  It does read like a subjective reporting from an NGO, but  when you're dealing with a difficult issue such as this, it is quite difficult to remain objective.  There have been changes in some of these countries with the introduction of robot jockeys, but there still remain serious concerns about driving this practice underground, making it harder to detect.  If you want to find out more about the treatment of some of these children, see Camel Jockeys of Rahimyar Khan (1.5 mb).  For a nationalist view of camel races in the UAE, see Camel Racing in the Gulf.
