Passage Three Police fired tear gas and arrested more than 5,000 passively resisting protestors Friday in an attempt to break up the largest antinuclear demonstration ever staged in the United States. More than 135,000 demonstrators confronted police on the construction site of a 1,000-megawatt rote/ear power plant scheduled to provide power to most of southern New Hampshire. Organizers of the huge demonstration said, the protest was continuing despite the police actions. More demonstrators were arriving to keep up the pressure on state authorities to cancel the project. The demonstrator had charged that the project was unsafe in the densely populated area, would create thermal pollution in the bay, and had no acceptable means for disposing of its radioactive wasters. The demonstrations would go on until the jails and the courts were so overloaded that the state judicial system would collapse. Govemor Stanforth Thumper insisted that there would be no reconsideration of the power project and no delay in its construction set for completion in three years. "This project will begin on time and the people of this state will begin to receive its benefits on schedule. Those who break the law in misguided attempts to sabotage(破坏) the project will be dealt with according to the law." he said. And police called in reinforcements from all over the state to handle the disturbances. The protests began before dawn Friday when several thousand demonstrators broke through police lines around the cordoned-offconstruction site. They carried placards (布告) that read "No Nukes is Good Nukes," "Sunpower, Not Nuclear Power," and "Stop Private Profits from Public Peril." They defied police order to move from the area. Tear gas canisters fired by police failed to dislodge the protestors who had come prepared with their own gas masks or facecloths. Finally gas-masked and hehneted police charged into the crowd to drag off the demonstrators one by one. The protestors did not resist police, but refused to walk away under their own power. Those arrested would be charged with unlawful assembly, trespassing(过失), and disturbing the peace. With whom were the jails and courts overloaded
