The tragic events in Aurora, Colo., have led to calls for new gun-control laws. Opponents rightly note such laws mostly disarm the law-abiding, and that regulations, rules and technology don't deter the determined. In fact, they can actually breed dangerous complacency.
Consider Daniel Casillo. After his jet ski ran out of fuel, Casillo swam to shore and climbed an eight-foot fence that's part of John F. Kennedy International Airport's state-of-the-art Perimeter Intrusion Detection System. He then walked nearly two miles across two runways before being spotted — wearing a bright yellow life jacket the entire time.
Or consider Liam Corcoran, an unaccompanied 11-year-old boy who successfully evaded five security checkpoints to board a British flight to Italy without tickets or a passport — and did it just days before the Olympics when security was supposedly at its peak.
That a jet skier can beat a $100 million system of surveillance cameras and motion detectors and a child can beat rigorous airport security measures shows technology is no substitute for human attentiveness, and can actually fuel a hazardous nonchalance.
