Tarmac Protest Raises Security Question

News out of London England reported that environmental protesters cut through the perimeter fence of Britain's third largest airport and occupied the tarmac. This forced the cancellation of more than 50 flights and raised questions over the vulnerability of airports. Two waves of protesters arrived at Stansted Airport before dawn. Using an old fire truck for cover, the first group sliced through the fence with bolt cutters. A second group ran through the gap. The action was meant to protest a possible second runway and escalating carbon emissions. Police arrested 57 people. They were right in arresting them for breaking in by cutting the fence.
