I've met Dr. Stein several times now, and I don't find this at all surprising. It's important to realize that the American hard Left has created a whole array of "crimes" for which one can be arrested symbolically, in a way that is viewed not as criminal in their context but as proof of personal commitment and virtue. One of the protest groups I met up in Philly had coordinated the process with the police, even, with both the police and the protest leadership having designated, armband-wearing 'liaison officers' to smooth the process of getting people arrested without actually disrupting the DNC in any important way. In return for playing along with your own arrest, you could be pretty sure of facing only administrative charges and a fine that would probably be dropped due to "incomplete" paperwork.
It's a sham, in other words.
Or at least it usually is, in Democrat-controlled cities. It sounds like the sheriff in North Dakota may not be aware that this is just a game people play to signal virtue. The Green Party says that the North Dakota police plan to file charges against her "for participating in civil disobedience against the Dakota Access Pipeline Tuesday morning." What she is actually charged with is "misdemeanor counts of criminal trespass and criminal mischief." That could land her in jail for more than a couple of hours in the afternoon: up to 30 days for a Class B misdemeanor, or up to a year if she was convicted of a Class A misdemeanor.
From a little more research, it looks as if the claims that this pipeline will endanger the water supply are not persuading many people to worry too much about it. However, the Feds are concerned about claims that the pipeline company is razing sacred burial sites and other cultural landmarks. It sounds as if at least some of these sacred sites have been rather hastily identified, to be sure, but on the other hand I'm also persuaded by the counterargument I heard this morning: how ready would we be to see a pipeline cut through Arlington? Arlington isn't even a fully sacred site, given its dedication to a secular state not devoted to any particular faith. It's only sacred in a sense, insofar as 'sacred' and 'sacrifice' are so closely linked. Arlington is sacred in the sense that it is where we honor those who have given their lives for our common good, as expressed in the defense of our nation.
UPDATE: "A judge on Friday denied the Standing Rock Sioux tribe's attempt to halt the construction of the Dakota Access oil pipeline near its North Dakota reservation, but three federal agencies asked the pipeline company to 'voluntarily pause' work on a segment that tribal officials say holds sacred sites and artifacts."
