This is the topic of a study coming out in September in which we're developing a psychosocial profile based on interviews. I can't talk too much about that right now.
The reasons are extensive and complex. I'll give you the example of an interview that I conducted with the leader of La Meute, Mr. Maikan. I asked him why his group came to intimidate us when we were giving a talk on the far right at the CEGEP. He told me that this was the only way for his group to be heard.
Some people in Quebec and, I think, in other parts of the world, feel that their voices aren't being heard.
