Another gun-free zones: Binghamton "13 Shot Dead During a Class on Citizenship"

Yet again look how incredibly long it took for someone with a gun to arrive on the scene here.  It is stunning that the attack "lasted up to three hours."  From the New York Times:

A gunman invaded an immigration services center in downtown Binghamton, N.Y., during citizenship classes on Friday and shot 13 people to death and critically wounded 4 others before killing himself in a paroxysm of violence that turned a quiet civic setting into scenes of carnage and chaos. 

The killing began around 10:30 a.m. and was over in minutes, witnesses said, but the ordeal lasted up to three hours for those trapped inside the American Civic Association as heavily armed police officers, sheriff’s deputies and state troopers threw up a cordon of firepower outside and waited in a silence of uncertainty. 

Finally, officers who had not fired a shot closed in and found a sprawl of bodies in a classroom, 37 terrified survivors cowering in closets and a boiler room and, in an office, the dead gunman, identified as Jiverly Wong, 42, a Vietnamese immigrant who lived in nearby Johnson City. . . .
