As a rule of thumb, there's lots of illegal stuff going down in Chinatowns all over North America. Want bootleg VCDs (I guess DVDs now), head to Chinatown. Want to eat snake, head to chinatown. Want martial arts weapons, head to Chinatown. When I was living in Toronto students made hajs every now and then to pick up DVDs at the Asian Mall. I think there was a bust at the mall ONCE, but it was because the store selling bootleg DVDs was a front (!!!) for other illicit activity. Much like copyright laws, I'm sure the store's owners don't care about weapons laws.
