Guilty! Make them clean the storage pool with tooth
Close the plant down. Let them go au natural
The judge could have had sport with this, using the technique of Civil War General Benjamin Butler, who met popular resistance when he was made the military occupation commander of New Orleans.
Butler’s General Order No. 28 of May 15, 1862, was that if any woman should insult or show contempt for any officer or soldier of the United States, she shall be regarded and shall be held liable to be treated as a “woman of the town plying her avocation”, i.e., a prostitute.
(It stopped the women’s protest against the Union Army cold.)
In this case, the judge could set things up to make an injunction against these women, that if they again protest at the nuclear plant, they are to be arrested on a charge of “soliciting for prostitution”, against the injunction.
This means they would not be brought in front of him on charges of prostitution, but for contempt of court, which does not merit a jury trial.
It works all the way around. It would be reported that the women were arrested for prostitution, they could each be given up to a year in jail for contempt. And they could neither mount a defense of protest or against the prostitution accusation.
