“It was scary,” said Kessler, who is a national organizer for the nonviolent environmental group Rising Tide North America. He said the agent approached him this past fall and said that the FBI had received an anonymous complaint and were looking into his opposition to hydraulic fracturing, also known as “fracking.” The bureau respected free speech, the agent told him, but was “worried about things being taken to an extreme level.”
the broad definition of domestic terrorism the FBI uses contributes to the number of investigations. According to its 2002-05 terrorism report, “A terrorist incident is a violent act or an act dangerous to human life, in violation of the criminal laws of the United States, or of any state, to intimidate or coerce a government, the civilian population, or any segment thereof, in furtherance of political or social objectives.”
As a result, any act aimed to intimidate an individual or corporation that has a political or social goal qualifies.
