Ummm Feehills, (and please never loose that handle, we know what you mean by it...), it is accepted by all crew and passengers that customs and excise officials have rights of search. What Akali Dal is questioning is do they have the right of racism. If his report is true, they believe that they do.
Profiling is acceptable if it is carried out in a way that would be acceptable to a jury, who after all would be the ultimate deciders in this if it came to court. Hopefully (but not always, unfortunately) the jury would be able to be colour blind to the incident.
As a white caucasian male I have been subjected to appalling abuse by indviduals of the Australian customs and immigration services. Thankfully these occasions are rare, and are mostly confined to the security staff who claim to be customs.
As I pointed out to an aggressive customs woman some time ago, she was a disgrace to her uniform and her country. Her colleagues within earshot could hardly stifle their laughter, as they knew that I was right.
