Sergeant-at-arms.

Seargent at arms.
A portrait of Sergeant-at-arms, Mr Ken Greenham. Drawn from the public gallery at the Nova Scotia Legislature. He carries a ceremonial mace, and is dressed in period costume—a relic of the past you may think.

But on October 22nd, 2014, it was another Sergeant-at-arms, Ken Vickers at the Ottawa legislature on Parliament Hill, who cast himself on a marble floor in-front of Michael Zehaf-Bibeau, and shot the armed intruder at point-blank-range.

His bravery and presence of mind prevented further bloodshed on that already bloody day.

(This drawing was previously posted last year but in light of recent events I decided to re-post).
