FBI Classification of Threat Risk Levels
Low Level of Threat: A threat that poses a minimal risk to the victim and public safety.
- Threat is vague and indirect.
- Information contained within the threat is inconsistent, implausible or lacks detail.
- Threat lacks realism.
- Content of the threat sugests person is unlikely to carry it out.
- Threat is made by young child (under 9 or 10) and there is laughter in the background.
- The caller is definitely known and has called numerous times.
Medium Level of Threat: A threat that could be carried out, although it may not appear entirely realistic.
- Threat is more direct and more concrete than a low-level threat.
- Wording in the threat suggests that the threatener has given some thought to how the act will be carried out.
- There may be a general indication of a possible place and time (though the signs still fall well short of a detailed plan).
- There is no strong indication that the threatener has taken preparatory steps, although there may be some veiled referece or ambiguous or inconclusive evidence pointing to that possibility-an allusion to a book or movie that shows the plannin of a violent act, or a vague, general statement about the availability of weapons.
- There may be a specific statememt seeking to convey that the threat is not empty: "I'm serious!" or "I really mean this!"
High level of Threat: A threat that appears to pose an imminent and serious danger to the safety of others.
- Threat is direct, specific and plausible. For example, "This is John Smith, I'm fed up with Mr. Jones yelling at me. There's a bomb under his desk."
- Threat suggests concrete steps have been taken toward carrying it out, for example, statements indicating that the threatner has acquired or practiced with a weapon or has had the intended victim under surveillance.
