OTTAWA SHOOTINGS

The Canadian capital suffered its second terrorist attack this week when a gunman fatally shot a soldier guarding the National War Memorial before entering the Canadian Parliament building and firing multiple shots yesterday. The assailant, Michael Zehaf-Bibeau, was shot dead by Sergeant-at-Arms Kevin Vickers outside the MP’s caucus room. [CBC News]  Zehaf-Bibeau was a convert to Islam and had reportedly already been designated as “high-risk” by authorities. [NBC News]

Both President Barack Obama and Secretary of State John Kerry condemned the “heinous and evil” attacks on “close” ally Canada, and Obama spoke by phone with Prime Minister Stephen Harper to express America’s solidarity with Canada following this week’s attacks.

The Ottawa attack is “a reminder of the threat the free world still faces,” according to the Wall Street Journal editorial board, which suggests that the Secret Service should consider what the attack indicates about the vulnerability of U.S. government buildings.

CBC News has live updates on the shootings and the police response surrounding Parliament Hill.

One bundle of weapons and supplies airdropped by U.S. forces in Syria likely fell into ISIS hands, a Pentagon spokesperson confirmed yesterday. However, Army Col.

BLACKWATER TRIAL

Four former Blackwater security guards were found guilty of charges related to the 2007 shooting at Nisur Square in Baghdad, Iraq, which killed 14 civilians and wounded many others.  [Justice Department]  The New York Times’ Matt Apuzzo has more details.

The New York Times editorial board writes that while the verdict “brings a measure of justice,” it does not “solve the problem of an American government that is still too dependent on private firms to supplement its military forces during overseas conflicts and is still unable to manage them effectively.”

Jeremy Scahill considers how only the low level soldiers are being held accountable for the Blackwater shooting, “[j]ust as with the systematic torture at Abu Ghraib.” [The Intercept]
