Bioterrorism is always a criminal act.
There is a low risk of a bioterrorism attack, moderate risk for bioterrorism threats, but there would be severe consequences if an event did occur.

Domestically, religious groups, anti-government groups, groups who want to make a statement about perceived wrongs or to demonstrate independence or individuals who are emotionally disturbed are those who are most likely to commit acts of bioterrorism.
