Since 9/11, there have been sporadic attacks on Muslims in Western countries, perpetrated by right-wing terrorists, but none has been more horrific and shocking than the coordinated assault on two mosques in Christchurch, New Zealand, after Friday prayers on March 15, 2019.
Anniversaries have a special significance in the terrorist calendar. This act of wanton religious violence took place several weeks after the 25th anniversary of the most infamous mosque shooting, in Hebron, Israel, on the morning of February 25, 1994. Baruch Goldstein, a doctor raised in U.S., entered the mosque at the Tomb of the Patriarchs, pulled out an assault rifle, fired 111 shots, killing 29 Muslims, injuring 125 others. It looks as if this carnage was surpassed in Christchurch.
Terrorist lone-wolves, like Baruch Goldstein, are hard to track because they leave only a small plot planning footprint. The Christchurch attack appears well coordinated and executed, and would have left a sizeable plot planning footprint, that security officials might potentially have detected.
