Members of the Canadian Parliament are praising as a hero House of Commons Sergeant-at-Arms Kevin Vickers, a former police superintendent, for his reported role in taking down the gunman who entered the building. Capitol Hill may be wondering if its own sergeants-at-arms usually pack heat. “I didn’t carry it all the time,” former Senate Sergeant-at-Arms Terrance W. Gainer said on C-SPAN’s “Washington Journal” Thursday morning. “I had it close at hand in a locked compartment.” Gainer, who served as chief of the Capitol Police before his seven-year gig in the Senate, said he frequently relied on the uniformed officers of the department. “We have concentric circles of security around here and so they are the first line of defense, but as the chief law enforcement officer, I was armed when I needed to be or thought it was appropriate,” he said.
