What speed bird said. There is no such thing as confidentiality in Dubai. Nothing is non-punitive and voluntary is in the military sense.
i.e. I need 3 volunteers, you, you and you. Right lets go!!
ClassC Mrs VT encouraged me to report things when I was in Dubai. Luckily I had learnt that lesson by the fate of those who went before me. Reporting stuff is fine after you leave but the reality is that you basically risk your liberty and the welfare of your family if you do so because they do not really want to know the truth they just want to seem to the rest of the world that you had an avenue available and decided not to use it and ergo there is not really any problem.
