One of the Canadian shooters, Michael Zehaf-Bibeau, recent convert to Islam, long criminal record

Michael Zehaf-Bibeau's name was apparently previously known as Michael Joseph Hall prior to converting to Islam.  He had been designated a high-risk traveler and that his passport had recently been confiscated.  Zehaf-Bibeau had a long criminal history with arrests for robbery, making threats, and various drug offenses.  He served time in prison on at least a couple of occasions (67 days for the uttering the threat), but he was still able to obtain a gun.  Apparently, he wasn't on the government's watch list of about 90 high-risk individuals and few under the radar.

This attack comes on the heels of another recent muslim convert who used his car to run over two soldiers in Canada, killing one of them.

Terrorist ideology inspired a recent convert to Islam to drive his car into two Canadian soldiers, killing one, before he was shot dead by police, authorities said on Tuesday.
Quebec police spokesman Guy Lapointe said the act was deliberate and that one of the two soldiers was in uniform. There were no other suspects. 

Public safety minister Steven Blaney called it a “terrible act of violence against our country, against our military and against our values” that was “clearly linked to terrorist ideology”. 

Police identified the dead military member as Warrant Officer Patrice Vincent, 53.
The suspect, Martin Couture Rouleau, 25, was known to authorities and recently had his passport seized, police commissioner Bob Paulson said. . . . 

Martin Couture Rouleau staked out the parking lot for 2 hours waiting for the soldiers.  He was apparently arrested in July, but was let go because he hadn't committed a crime and they did not view him as a threat to others.

Sadly, but not surprisingly given these two attacks on soldiers, the Canadian government is urging members of the military not to wear their uniforms when they are off duty.  In the attack today, the ceremonial guard who was in uniform was definitely targeted.

Possibly the weapon used in the attack was a shotgun.  Reports from the Chicago Tribune to the CBC indicate:

"He was wearing blue pants and a black jacket and he had a double barrelled shotgun and he ran up the side of this building here and hijacked a car at gunpoint," construction worker Scott Walsh told Reuters. . . .

In Jerusalem, an Arab terrorist rammed his car into a crowd, killing an infant and wounded several others.

A three-month-old girl, identified by her grandfather as Chaya Zissel, was killed and several US citizens and Israelis were wounded Wednesday evening when a convicted Palestinian terrorist from the east Jerusalem neighborhood of Silwan rammed his vehicle into a crowd of people in the capital. . . .
