Earlier this week, Dongdong Huang, a well-known lawyer in Vancouver was wrongfully detained and questioned on a business trip to China. He was accused of being involved in human trafficking. His humiliating ordeal began when a security official searched his carry-on bag and discovered a number of Chinese passports. Huang was on his way to China to return the passports, which belonged to his clients. His clients had lost their bid for seasonal work visas in Canada.
This appears to be a classic case of racial profiling where state officials over-react to equivocal conduct and refuse to accept the reasonable explanation offered by the person being questioned. According to the Globe and Mail story linked above, Customs officials "appeared incredulous when he said he was a lawyer."
