The issue has many similarities to the abortion debate: two polarized groups, both very certain that they are in the right, fighting for control over the piece of sidewalk out in front of some building that represents the issue (abortion clinics in one case, the Chinese consulate in another).
But B.C. manoeuvered very carefully on that issue. The "bubble zone" law prevents protesters from setting up within 50 metres of the entry of an abortion clinic. The reason the law was able to sustain a free-speech challenge was because the courts ruled that a woman's right to medical treatment trumps freedom of speech.
How do you make that defence in the Falun Gong case? As irritating as it must be for the Chinese consulate to have to deal with protesters outside every day, I have to think it pales beside the right of the peace-loving followers of a religion to protest the killings, assaults and harassment that plague their peers in China.
