Lone Wolf (terrorism)

Lone Wolf (terrorism)

A lone wolf or lone-wolf fighter is someone who commits or prepares for, or is suspected of committing or preparing for violent acts in support of some group, movement, or ideology, does so alone, outside of any command structure and without material assistance from any group.

In the U.S. legal context, the lone wolf is associated with the U.S. terror-law FISA, bearing in mind that U.S. terror-law comprises non-violent, as well as violent acts. Moreover, a lone wolf can be so defined on the mere basis of suspicion ("reasonable belief", not actual charges). Probable cause is not required.
