NDP MP Don Davies regrets Twitter misfire after bomb threat at Parliament Hill

A brief threat at Ottawa's Parliament Hill ended without incident on Wednesday after a suspect with a suspicious package was arrested shortly before parliament was to resume with the readsing of the Throne Speech.

CBC News reports that RCMP officers evacuated the Langenin Block, which houses the offices of the Privy Council and Prime Minister Stephen Harper.

It was a tense moment of drama amid a day expected to be filled with political gamesmanship and, unfortunately, one NDP MP launched a misdirected attack on Twitter.

Don Davis wrote, and later deleted, suggesting the man with a suspicious package was Harper with a speech "claiming to support consumers."

Davis later expressed relief that the situation came to a safe conclusion and issued a mea culpa.

As is often the case with Twitter misfire, the reaction was unkind toward Davis.
