What is the theme in Wild Justice by Wilbur Smith?

Terrorism is the main theme of the book. With the current system of justice, terrorism definitely has the upper hand. Even if a plot is uncovered, there is little that the government agencies are allowed to do by law. Certainly, items that relate to a terrorist attack could be impounded, and in some cases, charges could be laid if it can be proven that a plot involving terrorism is in play, but in all likelihood, the perpetrators would be back out on the streets in a very short time, wiser and prepared to begin again with a more cohesive plan. Terrorism is rampant in the world today.
