Michael Stohl from the University of California, Santa Barbara has been researching terrorism for many years, and in attempting to get a grasp on a more comprehensive definition, he identifies ten myths of terrorism.
1. Political terrorism is exclusively the activity of non-governmental actors.
2. All terrorists are madmen.
3. All terrorists are criminals.
4. One man's terrorist is another man's freedom fighter.
5. All insurgent violence is political terrorism.
6. The purpose of terrorism is the production of chaos.
7. Governments always oppose non-governmental terrorism.
8. Political terrorism is exclusively a problem relating to internal political conditions.
9. Devil theories of cause: The source of contemporary political terrorism may be found in the evil of one or two major actors.
10. Political terrorism is a strategy of futility.
These are, of course, only subtitles and the full article is called "Demystifying Terrorism: The Myths and Realities
of Contemporary Political Terrorism" ( from the book: THE POLITICS OF
TERRORISM, Marcel Dekker, Inc, 1983)
where he says: "Political terrorism is theater. It is profound and often tragic drama for which the world is the stage. Violence, death, intimidation, and fear are the theatrical ingredients. The plot often involves hostages, deadlines, and high-level bargaining. Tension and anxiety levels are immediately raised. National and international news media frequently monitor and broadcast terrorist events as they unfold. Law enforcement officials and sometimes insurgent terrorists are interviewed via on-the-scene minicameras, and speculations abound about the nature of the response that we might expect from both the authorities and the terrorists.
The central ingredients are present in all forms of terrorism, as in the legitimate theater, but only certain plays are given prominent reviews and fewer still become hits. Likewise, only a few actors and directors achieve stardom."
The definition of terrorism is certainly one that will continue to invoke colorful discussions. When trying to get a better grasp on it, it is important to consider economic, social, and historical contexts (amongst other things), as an act of terrorism is rarely a black and white occurrence.
The media plays a huge role in how the public perceives a terrorist act. If we look at the 7/7 London bombings, some outlets framed it as an externally orchestrated act (namely some US outlets alluding to AlQ etc) whereas other outlets framed it as a homegrown threat. The media, therefore acts as one of the principal framing agents, and the particular frame an act of terrorism is presented through has profound societal effects. Depending on how the threats are perceived, communities may be willing to give up social freedoms. Patriot act was very swiftly approved.
In regard to photography, other than embedded photographers covering "insurgent" or opposition fighters in Syria, for example, there doesn't seem to be much work involving more traditional cells such as Al Shabaab and Al Qaeda. This is likely due to difficulty of access and the operational secrecy that surrounds them. Also, you never know, as you're clicking away at a Somali training camp, a quiet little drone may be ready to drop its payload just over your head.
