I got thinking about this incident as I read these posts ...

One day in 1984, a crazed soldier named Denis Lortie went into the Quebec legislature and shot and killed three people, and wounded 13 others. As he sat in the Speaker's chair firing rounds from an automatic weapon at people cowering behind the seats, the commissionaire, who had just arrived at work, poked in his head to see what was going on. He quickly sussed out the situation - and began talking to Lortie. He persuaded him to let everyone go, then talked him into coming to his office. There, he continued to talk with him for about three hours, finally persuading him to surrender.

This newscast is here. The commissionaire, Jalbert, is seen near the end, walking out of the legislature with an unlit cigarette in his mouth, cool as a cucumber.
