Yes. Many of those audiotapes were actually made public. CBC published one. I believe that was an exclusive use, so I cannot use it, but it is on the CBC's website: One of the family members was phoned from Iran and basically threatened not to take any action.
On another occasion, it was Iran's foreign minister's audiotape that was revealed: Mr. Zarif, who many people in the west think is a reformer. He said this case will not go anywhere because they knew it; they knew what they wanted to do, and I'm afraid that this will not go anywhere. He tried to whitewash the whole regime
Unfortunately, this is not the only case. His department was also implicated in terrorist acts in other countries, including in Belgium. An Iranian diplomat, for the first time ever after World War II, was condemned and convicted on terrorism charges. He was convicted of having placed a bomb at a gathering of hundreds of thousands of Iranians in Paris. He was given the maximum sentence of 20 years, with no chance of parole or appeal.
I know from my own city, Ottawa, a radio host who has done this. She was threatened, actually by a gun to the head of her brother from Iran, calling on her to stop her work or to return back to Iran, otherwise her brother would be in danger.
These are the types of things we see quite often.
