On Tuesday, October 31, 2017, Sayfullo Saipov rented a truck in Passaic, New Jersey, and less than an hour later around 3pm was barreling down the scenic Hudson River Bike Path, mowing down runners, pedestrians and bikers alike. Victims and fatalities were found at different points along this 10-block killing spree, finally ending when his truck crashed into a school bus parked outside Stuyvesant High School.

Saipov was gunned down and captured by police who happened to be in that area investigating another incident. By the time the day ended, 6 people were killed on the spot, with two more dying later in the day.

This was the worst terrorist attack on New York City since September 11, 2001.

I feel pained at the loss of life and the inability to make sense of the murderous actions of this terrorist in my home town of New York, the frustration heightened by the fact that Saipov was apprehended outside my high school alma mater. Stuyvesant was only four blocks from the World Trade Towers, and thus ended up serving as a triage center for those injured and dying after the 9/11 attacks. On Tuesday, it served yet again as a backdrop to incomprehensible hatred.

A few weeks ago, the Economist Intelligence Unit (EIU) published their 2017 Safe Cities Index. In the dimension of “Personal Security”, which reflects the level of urban crime, violence or the likelihood of terrorism, New York City ranked 25th out of 60 cities surveyed. After seeing citizens run down on a bike path on a sunny afternoon, one might wonder why that ranking isn’t worse.

But on the whole, when EIU looks at all factors of security relevant to big cities, including digital, health and infrastructure safety, New York City ranks fourth safest in the world for cities with populations of 15 million or more.

At the top of the list, as the safest of the biggest cities, is Tokyo. In fact, Tokyo continues as the safest city in the world, maintaining its EIU reign since 2015. With the coming 2020 Tokyo Olympics, the public and private sectors in Japan are both working on measures to improve security, particularly in regards to digital security. While bombs and gun attacks are concerns, even in super safe Japan, great attention is being paid to ensuring Japan’s power grids, transportation systems, and digital platforms are not compromised now, or doing the 2020 Tokyo Olympics.

The Japanese are highly detail oriented and biased towards checking and re-checking for points of weakness and flaw, which is something I and many others can take comfort from if we dare to think about how creative and diabolical terrorist and crime organizations can be.

And yet, how do you protect against someone renting a truck and plowing into a crowd?
