While I don't nesessarily agree with the government being able to randomly stop and search people, I do agree with profiling. Statistics exist for a reason, I've been stopped on occasion by immigration officers where if I were and old white grandma I'd have been waved through no questions asked, did I get mad scream racism, sexism, ageism, whateverism? No I remained calm understood why I was stopped and cooperated. They were just doing their job, who's more suspicious a young solo male traveller with no current employment or a grandma visiting family?
