Everyone knows guns used by Canadian criminals are often smuggled from the U.S. Not everyone knows how — not like Naomi Haynes does. That's because she did the smuggling.

A native Montrealer who's been living in the U.S. for decades, she helped traffic dozens of weapons into Canada, some linked directly to drug gangs.

"I wasn't thinking about the havoc I was causing in my birth land," she told CBC News last week.

"I've got my kids, I've got bills. The only thing I [was] thinking about is monetary gains. I wasn't thinking about the people who are going to be affected."
