I’m pretty sure we’re supposed to find this reassuring:
The American electorate may not tolerate draconian (by U.S. standards) restrictions on guns, but it will tolerate a fair amount of surveillance. License-plate readers track our travels. Cellphone towers can triangulate our location. Face recognition is increasingly deployed in conjunction with security and traffic cameras; in China, police officers have it built into their spectacles. Not to mention the stupendous amounts of personal data we willingly hand over to businesses.
Now take all the red flags raised by Nikolas Cruz : He posted on social media pictures of himself with weapons and small animals he had apparently tortured. His fascination and exhibitionism with guns was broadcast to one and all. Teachers were warned to take action if he was seen approaching the school with a backpack; he later was expelled.
He was widely regarded as a menace. His mother, neighbors and school officials had repeatedly sought police intervention. He posted a YouTube comment under his own name in which he declared a desire to become a “professional school shooter,” one of two warnings passed on to the FBI.
Big data may not be better than psychologists at predicting who will commit a mass shooting a year or two from now, but it can help us know who might be planning one next week: Who got kicked out of school, failed to show up for a court-assigned counseling session, made a big purchase at a gun store, posted a deranged or threatening message on social media, prompted an uptick in alarmed social-media chatter by friends and acquaintances.
Especially since the young already conduct their social existence mostly online. Information technology is taking over our lives. It will not be uninvented. In another few years, unless you cut yourself off from the network (which will arouse its own suspicions), you will be findable in seconds. A police drone overhead will be able to focus its cameras on you or the vehicle or building in which you are to be found. Indeed, London cops caused a furor by innocently posting on Twitter the visage of a TV comedian snapped by an overhead camera looking down on the masses in Leicester Square. If it can’t already, soon this technology will be able to sound an alarm if a specific person on a list approaches a school or other sensitive site.

In fairness, though, this is likely to be more efficacious than the nostrums of the gun control lobby or the anodyne “thoughts and prayers” promised by Congressmen.
