From FBI link: In using the term Domestic Terrorism, DHS looks to the Homeland Security Act definition of terrorism, 6 U.S.C. 101(18), which is substantially similar but not identical to the title 18 definition. That provision defines terrorism as any activity that:
• Involves an act that: o Is dangerous to human life or potentially destructive of critical infrastructure or key resources; and o Is a violation of the criminal laws of the United States or of any State or other subdivision of the United States; and • Appears to be intended: o To intimidate or coerce a civilian population; o To influence the policy of a government by intimidation or coercion; or o To affect the conduct of a government by mass destruction, assassination, or kidnapping.
To everyone pointing out that he won’t be charged, OP’s question was can he be charged. Yes we get that it’s unlikely given the current configuration of us gov’t, but do his actions meet the basic requirements? Yes, absolutely.
That said, most billionaires probably meet the definition.
