What is one sign that a potential shooter may exhibit during the fantasy stage?

In the context of identifying potential shooters, the fantasy stage is often characterized by a strong inclination towards thoughts and daydreams about committing violent acts. Making web postings can serve as an essential sign during this stage as it reflects an individual's thoughts, feelings, and intentions that are often shared with an audience, signaling their fixation on violent fantasies.

Such online activity is not just a passive expression; it can include sharing disturbing content, discussing violent ideas, or expressing anger and resentment towards specific individuals or groups. This behavior serves as an indicator that the person may be moving beyond mere thoughts and is starting to externalize those dangerous fantasies, which can be a precursor to more serious actions.

While the other options represent concerning behaviors associated with different stages of planning or preparation for violence, making web postings specifically aligns with the fantasy stage by highlighting the individual’s mental state and the ideation of violence before any tangible actions are taken.
