In Canada selection for WBI is truly random, use is optional, the opt out pat down is usually professional and different from the 'new' TSA pat down, and CATSA is generally much more professional than TSA. Nor is WBI in use as much as in the US, and domestic and international flights do not follow all the TSA mandated rules for US bound flights.

Hence the reasons I suspect why it hasn't raised the same level of anger. Many of us have said it here - if TSA were at the same professional level as screeners in Europe or Asia most of the problems would not exist.
