Which of the following actions is considered "domestic terrorism"?

The action identified as domestic terrorism involves criminal acts aimed at intimidating civilians. This definition aligns with the broader understanding of terrorism, which is characterized by the use of violence or threats to instill fear and coerce a population or government. Domestic terrorism specifically refers to acts of violence within a country's borders that are politically motivated and directed at achieving specific goals through intimidation or coercion.

In contrast, peaceful protests, political discussions, and the distribution of fact-based information are all examples of engaging in civic activities, discourse, or advocacy. These actions do not involve violence or intimidation; rather, they represent fundamental rights in a democratic society, such as the rights to free speech and assembly. Thus, they do not meet the criteria outlined for domestic terrorism.
