A different approach which IMHO works very well. The author is Raffaello Pantucci, from RUSI and a SME on lone actor(s) / lone wolves. He explains:
...explains the theory behind lone-actor terrorism and what we know about lone actorsí effectiveness, motives and behaviours that could help us to better understand and disrupt future attacks.

An example of the comic approach.

There are two separate thread on lone actors:Lone Wolves in the USA (new title)
and Lone Wolves: outside the USA
