Security and counterterrorism procedures are often adaptive, for better or for worse. As attackers devise new methods to stage their assaults, authorities change their procedures accordingly. Following a recent attack in London, some people have been calling on British security services to do just that. At approximately 2:40 p.m. March 22, Khalid Masood jerked the steering wheel of his rented Hyundai Tucson sharply to the left at the entrance to London's Westminster Bridge, jumped the curb and pressed the accelerator.
Speeding along the sidewalk, he struck pedestrians who could not get out of his way; two people even jumped off the bridge to avoid being hit. As he neared the end of the bridge, Masood re-entered the roadway and sped toward the British Parliament building. He again jumped the curb to target more pedestrians before crashing into the building's perimeter fence shortly after passing Big Ben. Masood then leapt out of the wrecked car and ran around the corner of the compound to the Parliament's main vehicle entrance, where he attacked an unarmed police officer with a knife before being shot by a police officer inside the grounds. Though the attack lasted only 82 seconds, it killed five people (including Masood) and injured 50 more, some of them severely.
