"When anything can become a weapon, that chips away at the hope that terrorist attacks are somehow predictable or controllable. It does not take any special skills or resources to obtain a van and drive it into a crowd of innocent people. All it takes is motivation."
"Years of research has found that fear can eventually divide and poison societies, hardening people against perceived outsiders, even causing them to abandon key values. This kind of attack, using one of the most ordinary objects of daily life, could heighten that effect.
The political scientists Marc Hetherington and Elizabeth Suhay, for instance, have found that when people who are usually open and trusting toward outsiders feel they are at risk of a terrorist attack, they become more likely to support harsh, authoritarian policies and more willing to sacrifice civil liberties in exchange for perceived safety."
