In at least 31 states, legislators and governors have introduced bills and orders since Standing Rock  that target protests, particularly opposition to pipelines

Nicholas Kusnetz reports for Inside Climate News:

The activists were ready for a fight. An oil Pipeline was slated to cross tribal lands in eastern Oklahoma, and Native American leaders would resist. The Sierra Club and Black Lives Matter pledged support.

The groups announced their plans at a press conference in January 2017 at the State Capitol. Ashley McCray, a member of a local Shawnee tribe, stood in front of a blue "Water is Life" banner, her hair tied back with an ornate clip, and told reporters that organizers were forming a coalition to protect native lands.

They would establish a rural encampment, like the one that had drawn thousands of people to Standing Rock in North Dakota the previous year to resist the Dakota Access Pipeline.

The following week, an Oklahoma state lawmaker introduced a bill to stiffen penalties for interfering with pipelines and other "critical infrastructure." It would impose punishments of up to 10 years in prison and $100,000 in fines—and up to $1 million in penalties for any organization "found to be a conspirator" in violating the new law. Republican Rep. Scott Biggs, the bill's sponsor, said he was responding to those same Dakota Access Pipeline protests.

The activists established the camp in March, and within weeks the federal Department of Homeland Security and state law enforcement wrote a field analysis identifying "environmental rights extremists" as the top domestic terrorist threat to the Diamond Pipeline, planned to run from Oklahoma to Tennessee. The analysis said protesters could spark "criminal trespassing events resulting in violence." It told authorities to watch for people dressed in black.
