Query: A good summary of what's been happening.

We think of terrorist attacks as something that should be the responsibility of governments. But as this book points out, most of the targets are not government buildings or institutions, they are businesses. Targets have certainly included aircraft and also banks, theaters, churches, buses, trains, pipe lines, gas stations, restaurants, department stores, hospitals churches and of course office building such as those at the World Trade Center.Security tends to follow the last successful attack. After 9/11 a tremendous amount of effort was spent on air line scurity, almost nothing on subways, bridges, tunnels - can you imagine the effect of blowing up a few of these in New York City?This is not a prescription of what to do to avoid or stop terrorist activity, as the title suggests, it is an introduction to the risks involved and an explanation of what is happening on a world wide basis as a result. A small book, it covers these aspects very well.
