Input: On Tuesday in New York   Sayfullo Saipov  29  a green-card holder from Uzbekistan in Central Asia and resident of Florida   responded to the call.
 He  drove  his  rented Home Depot truck from West Houston Street onto a Hudson River Park bike path  one of New Yorkâs most beloved amenities. Within ten minutes  eight people were killed and 15 were injured. A note found in the truck  law enforcement officials said  indicated that  Saipov  committed the attack out of devotion to ISIS.
 Saipov  might have killed even more people had the NYPD not been the nationâs premier counterterrorism force. NYPD officers showed up in force minutes after the attack began  shooting  Saipov  before he could kill even more New Yorkers.
But it takes a pack to raise a lone wolf. Even if  Saipov  acted alone   he  was part of a growing ideological fraternity numbering in the tens of thousands who now inhabit every region of the globe.
Like the attacks in these cities  the Halloween attack in Lower Manhattan was aimed at inflicting maximum carnage. Schools in the area were letting out students shortly after three oâclock when  Saipov  drove  his  rented truck off West Houston Street onto the bike path.
There was no shortage of targets. The streets between West Houston and Chambers were crowded with parents picking up their costumed children prepared for an evening of trick-or-treating. Pedestrians and bikers on the Hudson River bike path were stunned and helpless as  Saipov  careened  his  weapon through the crowd.
 Saipov  might have killed even more people had the NYPD not been the nationâs premier counterterrorism force. NYPD officers showed up in force minutes after the attack began  shooting  Saipov  before he could kill even more New Yorkers.
