When I became the newest Member of Parliament from London North Centre, Kevin Vickers congratulated me. At the end of that day I walked up to Vickers and thanked him for his attention to detail and for his warm welcome. "I'm pretty new here myself, but you get used to it," he responded in that comfortable manner of his. Well, there are some things you just can't get used to, and nobody can testify to that reality better than Mr. Vickers himself. Just a few hours ago, he went from being a ceremonial Sergeant-at-Arms to a modern-day hero taking the lead in eliminating a gunman who, in that moment, brought the entire Parliamentary operation to a standstill.
