Standing ovations greeted the sergeant-at-arms in the Commons.

Expressionless much of the time, Kevin Vickers did appear close to tears at one point.

He’s released a statement saying he is ”very touched” by the attention he’s received after being credited as being the one who finally stopped the gunman who killed a soldier at the National War Memorial and then stormed Parliament Hill.

But Vickers points out he has the support of ”a remarkable security team” that demonstrated professionalism and courage during extraordinary circumstances.

He also offers deepest condolences and prayers on behalf of the Commons Security Services team to the family of Corporal Nathan Cirillo, killed at the War Memorial.

Vickers adds their thoughts are also with Constable Samearn Son, a member of the security services team, who was wounded in the leg.

Meanwhile, the mother of the shooter asks how can one ever explain something like this.

Susan Bibeau says she’s crying for the victims, not her son and that she doesn’t know what to say to those hurt in the attack.

She adds she was mad at her son and that part of her ”wants to hate him at this time.”

Bibeau says he seemed lost ”and did not fit in” but  had little insight to offer because she hadn’t seen him in five years, until she had lunch with him last week.
